ECONOMIC REFORM AND FUNCTIONAL CHANGES OF THE AUTHORITIES OF BURYATIA IN THE LATE 1960S – 1970S
Authors: Protasov E. T.
Published: July 2017

The subject of the research is the analysis of economic and structural changes  in  the  country  and  the  autonomous  republic  in  the  examined  period with the use of the systemic and comparative approaches, as well as institutional research method. When planning the economic reforms, the USSR and the Buryat ASSR bodies of state power and control did an active and purposeful job to implement them and carried out an effective personnel policy. In 1965 – 1966 the territorial management system was abolished in industrial production. Branch management was passed on to newly created ministries, the role of state committees increased. These facts created auspicious conditions for scientific and technical progress development. Moreover, the main purpose of the production was the course on development and inculcation of economic management methods, independence of enterprises, and reduction of administrative regulation of their activity. The results of economic development during the 8th five-year plan were the best for the whole Soviet period. At the same time, macroeconomics still maintained an extensive character. The provided materials interpreted in a modern light can be used for reconsideration of state governing bodies’ formation and evolution.
SOCIAL AND POLITICAL LIFE OF WORKERS AND EMPLOYEES OF DEFENSE INDUSTRY IN WESTERN SIBERIA DURING THE GREAT PATRIOTIC WAR
Authors: Sawicky I. M.
Published: July 2017

The article considers the socio-political life of the workers and employees of the military-industrial complex in Western Siberia, which is one of three such complexes  in  the  USSR  that  supplied  the  Red  Army  with  military  equipment and ammunition. It was established that the Central Committee of the All-Union Communist Party of Bolsheviks (CPSU (b), giving great attention to the regions of their location, in the Propaganda and Agitation Department of the Central Committee  added  some  new  structural  units,  whose  influence  embraced  all  aspects of socio-political life of the workers and employees in these regions. Propaganda and Agitation Department of the Central Committee promptly controlled and supervised the work of local Party and Soviet bodies, organizations and institutions in this direction.

The major focus is on the study of the activities of the Soviet Information Bureau (Sovinformbureau), press, radio, cinema, lecturers, propagandists and agitators, who informed the workers and employees about the most important events at the front and in the rear, formed the social and political attitudes. It was found that the greatest role was played by outstanding artists, theatrical, musical and artistic intelligentsia who, through their presentations, shows and performances of the anti-fascist orientation raising the spiritual forces of workers, engineers and technicians, inspired people to labor feats. Through the combination of these events, organized by the central and local Party authorities, the government and local executive authorities shaped social and political consciousness, patriotism of workers, engineers and technicians, to forge the weapon of victory over fascism.
Kontrola abuzywności postanowień umów bankowych dotyczących ubezpieczenia niskiego wkładu własnego. Glosa aprobująca do wyroku Sądu Okręgowego w Warszawie z 27.10.2016 r. (XXVII C 3361/16; niepubl.)

Glosa odnosi się do wyroku Sądu Okręgowego w Warszawie z 27.10.2016 r. (XXVII C 3361/16) dotyczącego uznania postanowień umownych związanych z ubezpieczeniem niskiego wkładu własnego za klauzule abuzywne. W związku z coraz częstszym stosowaniem przez banki w umowach kredytowych dodatkowego zabezpieczenia,jakim jest ubezpieczenie niskiego wkładu własnego powstała konieczność rozważenia czy nie stanowi ono świadczenia nienależnego, o którym mowa w art. 410 § 2 kodeksu cywilnego wskutek uznania odpowiednich postanowień umowy kredytowej za klauzulęabuzywną. Stosowanie przez banki klauzul abuzywnych w wykorzystywanych przez nie wzorcach umownych przysparzało korzyści majątkowej poprzez obciążenie konsumentów kosztami zawarcia przez banki z ubezpieczycielem generalnej umowy ubezpieczenia niskiego wkładu w kredytach i pożyczkach hipotecznych, co bezpośrednio skutkowało wzbogaceniem banków o pobierane od konsumentów kwoty z tytułu kosztów przedmiotowego ubezpieczenia niskiego wkładu.
Glosa aprobująca do wyroku Sądu Najwyższego z 21.10.2016 r., V CSK 26/16
Authors: Polus Agnieszka
Published: July 2017

Glosowane orzeczenie dotyczy pytania, czy postępowanie sądowe w wyniku którego doszło do uchylenia decyzji (o którym mowa w art. 287 pkt 1 ustawy z 30.8.2002 r. Prawo postępowaniu przed sądami administracyjnymi), może zostać uznane za „właściwepostępowanie” zmierzające do stwierdzenia niezgodności z prawem decyzji administracyjnej (art. 4171 § 2 Kodeksu cywilnego). Sąd Najwyższy stanął na stanowisku, że art. 287 pkt 1 ustawy Prawo postępowaniu przed sądami administracyjnymi może być rozumiany także w ten sposób, że przewiduje dodatkową przesłankę odpowiedzialności odszkodowawczej za szkodę wyrządzoną wykonywaniem władzy publicznej, która zachodzi wtedy, gdy wpostępowaniu administracyjnym prowadzonym w celu wykonania uchylającego decyzję wyroku sądu administracyjnego dojdzie do umorzenia postępowania. Na poparcie tezy Sądu Najwyższego warto przytoczyć dwa argumenty: po pierwsze, art. 287 pkt 1 ustawy Prawopostępowaniu przed sądami administracyjnymi nie zawiera pełnego unormowania odpowiedzialności odszkodowawczej za szkody spowodowane decyzjami administracyjnymi, które następnie zostały uchylone przez sąd administracyjny; po drugie, przepis ten niewskazuje podmiotów właściwych do orzekania w sprawach o odszkodowanie, nie określa też zakresu odpowiedzialności, ani zasad wymiaru odszkodowania.

The   paper   presents   data   analysis   of  the   Hip   Arthroplasty  Register   of  Vreden   Russian   Research   Institute of Traumatology and Orthopedics, namely information on 37373 primary THA performed at the Vreden Institute and at several other orthopedic centers and 1200 hip replacements at other hospitals of St. Petersburg.There were 1.5 times more women in the studied cohort than men. A significant predominance of women with dysplastic osteoarthritis (72.4%) and rheumatoid arthritis (82.1%) was reported. A male predominance was noted in patients with secondary osteoarthritis (53.1%), post-traumatic changes of hip (61.0%) and osteonecrosis of the femoral head (68.6 %). The mean age of patients was 58.0±12.9 years (95% CI from 57.9 to 58.1, median 59 years). Age data of the study revealed that  patients were 10-12 years younger than reported in the national  arthroplasty registers of other countries.Total  hip arthroplasty was performed  in the  absolute  majority  of patients – 37295  cases (99,8%).  Uncemented implants  were used in 59.3% of cases, hybrid – in 29.6%, cemented – in 10.2%, reverse-hybrid – in 0.9% of all patients.

The Illusion and the Reality of Chinese Budget Reforms: Does Budgeting Influence Corruption Perception?
Authors: Zhang Ji
Published: July 2017

Anti-corruption campaigns have been part of Chinese governance for decades. In the late 1990s, the government began to transform its anti-corruption efforts into a permanent institution, and the effect on corruption control caused by budget reforms started to emerge. Some studies have discussed and explained how the transformation of government's financial structure and performance would reduce rent-seeking motives and control corruption at the provincial and central level. Whether those financial changes could also affect corruption perception at the individual level still needs to be verified. This study uses Chinese data (2010–2012) from the third wave of the Asian Barometer Survey (ABS) to explore how objective performance achieved by budget reforms affects subjective corruption perception. It also examines the citizen empowerment effect and its interaction effect with financial variables on corruption perception. The conclusion suggests that budgeting has a larger influence on the corruption perception of local government than on the corruption perception of central government. As budget transparency and audit have improved, local government should be perceived as less corrupt. Furthermore, budget transparency will gradually develop a new and different means for the public to supervise local government activities rather than through a formal political process like an election. Those citizens with low citizen empowerment will get more information from budgeting disclosures and may not think the government is corrupt. In addition, the budget deficit has non-linear effects on the corruption perceptions of both the local and the central governments.
O sentido da Ressurreição de Jesus na escatologia de Jürgen Moltmann
Authors: Cunha Gladson Pereira da
Published: July 2017

O presente artigo é uma revisão sobre o sentido que o teólogo reformado Jürgen Moltmann dá, em sua escatologia, ao evento da Ressurreição de Jesus Cristo. Esse evento é o tema central nos dois principais trabalhos de escatologia de Moltmann, a Teologia da Esperança, que abre a sua reflexão para o lugar da própria ressurreição de Jesus como objeto da esperança humana, mediante a promessa divina da ressurreição da humanidade dos mortos, uma doutrina de suma importância para o cristianismo, e O Deus Crucificado, no qual a esperança e o evento da ressurreição são retomados. Basicamente o artigo é construído sob uma revisão da bibliografia moltmanniana, seguida de uma reflexão sobre ela, procurando demonstrar o entendimento de Moltmann diante da ressurreição do Crucificado.
Pastoral Popular Luterana: O Testemunho de uma Prática
Authors: Schmitt Flavio
Published: July 2017

A migração é parte da caminhada de povos e culturas. Em geral, migrantes são portadores de crenças e costumes. Ao partir levam consigo valores, tradições e crenças. Com os migrantes que deram origem à igreja luterana no Brasil não foi diferente. Além dos elementos culturais trazidos da Europa, ao se deslocarem dentro do território brasileiro carregam consigo os elementos trazidos do estrangeiro e os agregados na nova pátria. Desta amálgama de valores, tradições e crenças vividas em diferentes contextos e desafios, brotam novas possibilidades e iniciativas. É este o cenário que dá origem à Pastoral Popular Luterana. Trata-se de uma iniciativa protagonizada majoritariamente por descendentes de imigrantes, vinculados à igreja luterana, e que procuram fazer frente aos desafios de um tempo particular. Este artigo trata da presença e atuação da Pastoral Popular Luterana no Oeste do Estado do Paraná, na década de 1980. Tem o propósito de tematizar a tarefa pastoral da igreja e fazer memória de uma prática.
Preciso de Ti: A relevância da religião no combate (reabilitação) as drogas
Authors: Da Silva Renan Antônio
Published: July 2017

A religiosidade e a espiritualidade continuam presentes nas sociedades desde seus primórdios. A crença no sobrenatural ou em um ou mais seres superiores tem se mostrado um fator de empoderamento das individualidades. Encontram-se na narrativa das várias denominações religiosas histórias de superação de dificuldades das mais diversas naturezas graças a valores religiosos que fortalecem a subjetividade. Esses valores estão sendo utilizados como coadjuvantes no tratamento de dependentes químicos. A igreja protestante foi a pioneira no uso da religiosidade nesse tratamento. No final da década de 40 implementaram programas de recuperação nas igrejas evangélicas norte-americanas. A partir da década de 60, a igreja católica também começou a realizar tratamentos de reabilitação baseados nos valores da fé cristã. Quanto à metodologia do trabalho, foram utilizados livros, revistas e internet relacionados ao assunto.
Protagonismo feminino, igreja e mulheres no ministério da Igreja Evangélica de Confissão Luterana no Brasil: a propósito dos 500 anos da Reforma
Authors: Burmann Claudir
Published: July 2017

A atuação das mulheres ao longo da história do Cristianismo quase sempre oscilou em direção à invisibilidade. Não porque não quisessem exercer e mostrar seu protagonismo. Mas porque seu espaço foi reduzido a quase inexistente pelas estruturas socioculturais em que o Cristianismo se desenvolveu. Mesmo que na origem do Cristianismo a partir de Jesus de Nazaré e nas primeiras comunidades cristãs as mulheres tenham exercido papel fundamental, as ideologias patriarcais e androcêntricas se impuseram nos períodos subsequentes. A Igreja se institucionalizou tendo homens como referência. Apesar disso, o registro do protagonismo feminino se manteve no Novo Testamento. Algumas outras mulheres desafiaram a lógica epocal e marcaram a história eclesial no período Medieval. Se a Reforma Protestante não reconheceu às mulheres seu protagonismo no seio cristão, possibilitou que paulatinamente se desenvolvesse. Na atualidade, em inúmeras instituições eclesiais, como na Igreja Evangélica de Confissão Luterana no Brasil, é reconhecido o ministério feminino em grau de igualdade a ministérios exercidos por homens. Entretanto, é um caminho árduo e sofrido para muitas mulheres que não desistiram e não desistem, impulsionadas pelas mulheres dos primórdios cristãos e pela conquista de direitos sociais em tempos recentes. É acerca dessa análise que o presente artigo se concentra.
O Sagrado no culto protestante reformado: uma reflexão desde dentro
Authors: Lopes Marcelo
Published: July 2017

O ano de 2017 é bastante simbólico para os protestantes, pois nele comemoramos duas datas bastante significativas: os 500 anos da Reforma Protestante e os 100 anos do lançamento do livro O Sagrado do teólogo protestante Rudolf Otto. De natureza preambular, o presente ensaio tem por escopo problematizar aspectos do sagrado no culto protestante reformado, tomando como referência a Igreja Presbiteriana do Brasil. O texto está estruturado em três tópicos: uma brevíssima sinopse histórica do culto reformado no Brasil, os dois modelos de culto mais adotados pelos protestantes; além, é claro, de problematizar sumariamente, aspectos do sagrado no culto reformado, e isso de forma endógena. Trata-se, portanto, de um esforço heurístico de iluminar uma temática cara, nesta data deveras expressiva.
The experience of employment of the mathematical cartography methods in cosmology
Authors: Kavrayskiy A.V.
Published: July 2017

The experience of mathematical modeling of the 3D-sphere in the 4D-space and projecting it by mathematical cartography methods in the 3D-Euclidian space is presented. The problem is solved by introduction of spherical coordinates for the 3D-sphere and their transformation into the rectangular coordinates, using the mathematical cartography methods. The mathematical relationship for calculating the length distortion mp(s) of the ds linear element when projecting the 3D-sphere from the 4-dimensional Euclidian space into three-dimensional Euclidian space is derived. Numerical examples, containing the modeling of the ds small linear element by spherical coordinates of 3D-sphere, projecting this sphere into the 3D-Euclidian space and length of ds calculating by means of its projection dL and size of distortion mp(s) are solved. Based on the model of the Universe known in cosmology as the 3D-sphere, the hypothesis of connection between distortion mp(s) and the known observed effects Redshift and Microwave Background Radiation is considered.
«El Día de Dios». Acerca del tiempo, según Franz Rosenzweig
Authors: Beltrán Ulate Esteban
Published: July 2017

Recibido: 06/01/2016 • Aceptado: 27/03/2017

 

Este artículo acomete el análisis de la concepción de temporalidad desarrollada por el filósofo alemán Franz Rosenzweig (1886-1929), a partir del escrutinio de su principal obra Der Stern der Erlösung  (1921), desde una perspectiva fenomenológica. El tiempo, ahí, se comprende en una tridimensionalidad, a la luz de la noción del «Día de Dios». El planteamiento del pensador judío evidencia una ruptura con las tesis filosóficas modernas, que presentan el tiempo como absoluto. En oposición a esta creencia, establece una relación entre redención e historia del mundo, donde la eternidad comprende, en su estructura, pasado, presente y futuro. En la primera parte, se expondrá una breve semblanza del casselense. A continuación, se presenta una exposición de la tradición judía sobre el tiempo, de la que se deriva una crítica a su concepción moderna. A continuación, se expone la doctrina sobre el tiempo que presenta La estrella de la redención  y, finalmente, se concluye  mostrando la relación entre temporalidad y eternidad como la expuso Franz Rosenzweig.

Límites de la comprensión gadameriana de la fenomenología
Authors: Expósito Ropero Noé
Published: July 2017

Recibido: 31/10/2016 • Aceptado: 02/02/2017

Este artículo persigue, en primer lugar, presentar la interpretación que Hans-Georg Gadamer mantuvo de la fenomenología de Edmund Husserl, incidiendo en las críticas que contra ella dirige. Para ello, se remite a la reciente publicación de El movimiento fenomenológico . En segundo lugar, pretende mostrar cómo la lectura gadameriana de Husserl está marcada por una serie de prejuicios y malentendidos que le impiden tener una comprensión adecuada de la fenomenología, y cómo las críticas de Gadamer a la fenomenología de Husserl se deben a dicha interpretación. Así, resulta que la fenomenología husserliana y la hermenéutica gadameriana sostienen menos polémicas de las que parecerían tener. A modo de conclusión, se expondrá muy brevemente la relevancia de esta problemática para el debate filosófico actual.

Published: July 2017

Reliable operation of transformers largely depends on a lifetime of insulating system. For this reason the paper deals with a description of our experience with developed monitoring system, which is focused mainly on a control of oil filling of experimental transformer. Relative humidity, amount of dissolved gases and increased temperature are observed, as they have decisive influence on insulating system of transformer. Monitoring of these characteristics is completed with analysis of oil samples by infrared spectroscopy in mode of Attenuated Total Reflection technique.
Development of a Low Speed Linear Generator for use in a Wave Energy Converter
Authors: J. Ribeiro  , I. Martins
Published: July 2017

One of the main advantages of ocean waves as
resource for electrical energy production is its high energy
density. Several methods have been proposed for the conversion
of ocean wave mechanical energy into electrical energy. One
such method consists in the use of a direct drive linear generator
enclosed inside a floating element. The generator is driven by a
mass-spring system, which oscillates due to the ocean wave’s
movement. In this paper are presented the study, development,
and dynamic simulation of a linear tubular synchronous low
speed permanent magnet generator, for use in a wave energy
conversion system. The generator was dimensioned using a
finite element analysis tool. The wave energy converter
dynamic model, mechanical and electrical, was developed to
evaluate its response. To validate the generator’s dimensioning
and dynamic model, its prototype was built. The dynamic
model simulation results and the prototype’s experimental
results are presented.
Conversion Analysis of a Planetary Chain-Set Speed Reducer into a Speed Increaser to Be Used in RES
Authors: C. Jaliu  , D.V. Diaconescu  , R. Săulescu  , O. Climescu
Published: July 2017

Most renewable energy systems (RES) require a
transmission to modify the input speed into the desired output
speed. The solar systems drive trains include a speed reducer,
while the wind turbines and hydro units’ usually contain a
gearbox to increase the speed of the input shaft to the generator.

The paper main objective is analyzing the conversion
possibilities of a proposed planetary chain-set from speed
reducer into a speed increaser, by inverting the energy flow.
The transmission is meant to be used in the RES applications
(small wind turbines and hydropower stations).
By inverting the energy flow, the reducer can become speed
increaser only if its efficiency is positive. Therefore, the
variation of the kinematical ratio i (first as reducer and, then, as
increaser) and the variation of the afferent efficiencies are
further analyzed comparatively, in the paper. The results
interpretation highlight the conditions in which the chain
transmission can be used as speed reducer and speed increaser
and form a data basis for choosing the proper solution of chain
transmission for a certain application (in terms of teeth numbers
and efficiency)
Characterization of fat mixtures with diesel combustion and process combustion fireplace at constant pressure
Authors: J. F. José Alonso  , J.A.López Sastre  , C. Romero-Ávila
Published: July 2017

This article studies the characteristics of fatty pork and animal by-products not intended for human consumption (in Spain SANDACH). We assess category 1 and 3 and mixtures thereof with diesel for use as fuel in a combustion chamber at constant pressure which has a mechanical pulverization burner pressure and emulsion. Characterization of fats and their blends with diesel fuel was based on four criteria: i) intrinsic chemical quality (composition of elements and ash), ii) mechanical quality (viscosity, density for different temperatures), iii) energy quality (calorific value) and iv) the mixing process of various fats with diesel. Finally, we conduct a study of possible technologies for use in a combustion process in a constant pressure chamber and we perform tests using a mechanical pulverization burner and burner pressure emulsion.
New Approach in Insulation System of Power Transformers – Insulating Oils with Less Impact on the Environment

Published: July 2017

Paper    deals    with    comparison    of    selected properties of several vegetable oil representatives(commercially  available  ENVIROTEMP®  FR3TM  vegetable-based   transformer   oil,   sunflower   oil,   rape   oil   and   refined sunflower  and  rape  oil)  along  their  accelerated  thermal  ageing at  the  temperature  of  90  °C.  These  properties  are  compared  to two    widely    used    and    commercially    available    mineral transformer   oils   (Technol   Y   3000   and   Shell   Diala   DX). Combined  insulating  system  (oil-paper  system)  was  created with  the  usage  of  mentioned  oils  for  measurement  purposes. Dissipation   factor,   capacity   and   volume   resistance   are   the characteristics  measured  along  the  thermal  ageing  of  the  oil-paper systems. Infrared spectroscopy was used as the additional method. After 1000 hours of ageing, the dissipation factor of all systems  based  on  vegetable  oils  did  not  exceed  the  value  of 0,015. The volume resistance of systems containing mineral oils was  approx.  twice  as  high  as  volume  resistance  of  those  with vegetable oils. Capacity on the other hand was slightly lower in the  case  of  mineral  oils  application.  Experiment  also  showed that paper combined with vegetable oil dries more quickly than in  combination  with  mineral  oil.  Infrared  spectroscopy  has  not shown  any  expressive  changes  in  the  chemical  structure  of  all tested  oils  yet.  It  was  proven  that  all  monitored  electrical properties  of  commercially  available  ENVIROTEMP®  FR3TMtransformer  oil  are  very  similar  to  the  properties  of  common rape oil.

Published: July 2017

Recent   development   of   dispersed   generation   technologies   employing   sustainable   energy   resources   has   encouraged  the  entry  of  power  generation  at  distribution  level.  The  close  distance  between  load  and  generation  reduces  the  network  losses.  However,  DG  system  with  electronic  devices  gives   harmonic   distortion.   Harmonics   introduce   additional   losses  and  could  cause  premature  ageing  as  well  as  earlier  re-investment  of  network  components.  This  paper  examines  the  network  losses  of  a  grid-connected  photovoltaic  (PV).  The  fundamental and harmonic losses of main network components, including transformer  and  cables,  are  calculated  and  compared  among three cases: 1) without PV, 2) with PV, and, 3) with PV and storage.
Advanced Doubly Fed Induction Machine Rotor Fault Diagnosis Based on Wavelet Analysis in Closed-Loop Operation Under Time–varying Condition

Published: July 2017

This paper introduces a new diagnostic technique
for the detection of incipient electrical rotor faults in doubly fed
induction Machine (DFIM) for wind power systems. In the
considered application, the rotor is supplied by a static
converter for the control of active and reactive power flows
from the generator to the electrical grid. A new diagnostic
method based on the rotor modulating signals pre-processing by
Frequency Sliding (FS) and Discrete Wavelet Transform
(DWT) thereby is here proposed to detect rotor faults
dynamically over time. Experimental and simulation results
demonstrate the effectiveness of the proposed approach under
time-varying conditions.

related to the made study and which will be of interest
With the given references, we can considerer the study finished.
Fast Tracking the Fundamental component in Synchrophasors applications using the Recursive Corrected Phase Wavelet Transform
Authors: C. D. P. Crovato  , V. Souza  , G. S. Wojichowski  , A. A. Susin
Published: July 2017

This paper presents the use of Recursive
Corrected Phase Wavelet Transform to track harmonic
components (always present in Power Systems), in order to
determine the fundamental frequency “as soon as possible”, to
provide appropriate input values to a non-linear algorithm that
can accurately approach in only one cycle the amplitude and
phase of the fundamental frequency. This technique is useful in
real-time synchrophasors applications, specially for load
identification and characterization. Based on the deepest
descend method, the algorithm has less computational effort in
comparison with phased locked loop.
Advanced Concept for Participation of Large Wind Farms in Ancillary Services
Authors: Ahmad-Rami Al-Awaad
Published: July 2017

The use of renewable energies is steadily growing. Wind energy is the main installed type of renewable energy in Germany. Wind power plants are concentrated in large wind farms. These wind farms are connected to high voltage grids. Despite the high level of installed wind power, wind farms have not contributed to voltage and frequency control (primary, secondary and tertiary control) until now. Wind farm owners receive a fixed payment from the transmission system operator for the energy they generate. This payment is much higher than the average variable costs of conventional power plants. This study shows that modern wind power plants and farms can also support voltage and frequency control. Wind farm owners receive more income through participating in frequency control than from the fixed payment for energy generated. This extra income can help to reduce the fixed payment for energy generated by wind farms.
A new method for identification of zones with similar wind patterns using Hierarchical Clustering Techniques
Authors: J. C. Palomares Salas  , A. Agüera Pérez  , J. J. G. de la Rosa  , J. G. Ramiro
Published: July 2017

In this paper it is shown a process to demarcate
areas with analogous wind conditions. For this purpose a
dispersion graph between wind directions will be traced for all
stations placed in the studied zone. These distributions will be
compared among themselves using the hierarchical clustering
algorithm. This information will be used to build a matrix,
letting us work with all relations simultaneously. By
permutation of elements in this matrix it is possible to group
relationed stations.
Reduction of Electric and Magnetic Field Emissions caused by Overhead Power Lines

Published: July 2017

Calculations and measurements of magnetic and
electric fields of overhead power lines existing in Slovenia
show that electromagnetic field emissions on the border of
overhead power line right of way could be too high. The
allowed electromagnetic field emissions defined by Slovenian
government in 1996 are very strict especially for newly
constructed overhead lines. For that reason some modification
should be applied for newly constructed overhead lines. This
paper proposed a few solution of aforementioned problem
regarding arrangements of overhead power line conductor.
ELECTRIC VEHICLE BASED ON STANDARD INDUSTRIAL COMPONENTS
Authors: José Fernández Ramos  , Foroohar Aghili Khatir
Published: July 2017

The aim of this paper is to presents the complete design of an electric vehicle by using standard industrial components as VRLA batteries, AC induction motors and standard frequency converters. In comparison with dedicated components, the use of standard components has the following advantages: higher reliability, low price, broad range of products and suppliers, and high availability and technological independence. Besides this, we show that these components allow to make an easy and efficient electric differential without speed or steering sensors and they can perform regenerative braking.

Published: July 2017

The  results  of  the  implementation  of  an  actual microgrid in the Netherlands are  presented.  This microgrid has photovoltaic  panels  as  microsources,  energy  storage,  and  a flexible  AC  distribution  system  (FACDS)  that  can  operate connected to the public grid or autonomously where it regulates the  site’s  voltage  and  frequency.  In  this  paper,  the  potential  of the  microgrid  in  improving  power  quality  issues  of  the  site, specifically  harmonic  distortions,  is  demonstrated.    Results show that the system was able to compensate voltage harmonics when the  microgrid was operating connected to the public grid and  when  operating  autonomously.  Other  tests  such  as  short-circuit,  synchronization  and  blackstart  were  also  conducted. The  improvement  in  power  quality  and  positive  results  of  the other  tests  demonstrate  that  a  self-supporting,  reliable  and efficient operation of the microgrid can be achieved.
Centralized normalization of harmonic voltages by the third-order passive filter
Authors: L.I.Kovernikova
Published: July 2017

The values of harmonic voltages at network
nodes should meet the standard limits. Harmonic voltages can
be decreased to admissible values on a centralized basis. The
paper addresses the problem of centralized decrease of
harmonic voltages in the high voltage networks with distributed
nonlinear loads using third-order passive filters. Mathematical
expressions to determine parameters of the third-order passive
filter are given. The parameters of the selected filters for 220
kV network supplying traction substations with power and also
the estimates of the efficiency of work of these filters for
different network configurations are presented as an example.
The efficiency of the C-type and third-order filters are
compared.
Agent-Based Services for Building Markets in Distributed Energy Environments

Published: July 2017

The safe integration of renewable energy sources requires distributed energy environments provided with reactive and  dynamic  management  systems.  To  this  end,  recent  works propose  creating  energy  micromarkets  in  which  producers  and consumers  are capable  of  negotiating  their  interests  by  using autonomous  software  entities.  Despite  intelligent  agents  are widely  accepted  as  a  suitable  technology  for  undertaking thistask,  we  point  out  that  their  adoption  entails  important  risks. Specifically,  this  paper  highlight  a  set  of  technological  and structural challenges that  implies the integration of agents  with distributed  energy  networks  and,  as  a  result, it  concludes  that new  contributions  are  necessary  in  the  modelling  field  for building  more  flexible,  reactive  and  scalable  networks.  With this  aim,  we  put  forward  a  new  agent-based  and  services-oriented   model   called   Agency   Services   that,   apart   from overcoming most   of   the   challenges   faced   by   the   current proposals, gives new capabilities.
Real Problems in Utility High Voltage Network due to Grid Connected Photovoltaic Power Generation. The experience of Endesa.
Authors: Javier de la Cruz  , Pedro Gómez
Published: July 2017

Photovoltaic (PV) systems require connection to a
utility power grid to work effectively as energy sources.
Numerous problems and unusual configurations have been
detected in those connections: Some problems are due to a
dysfunction of the faulted-phase relay protection on Substations
(Sub.) not originated in all cases by phase imbalance of the PV
inverters, other problems are related to an abnormal stationary
(resonant) state of generation just after islanding of the plant,
where frequency and amplitude of the power signal are in a
corrupted stable state caused by the inverters. The final problem
to be discussed is related to switch-on sequencing and
associated starting inverter’s problems.
Ni and Ni-Fe perovskite for catalytic abatement of tar
Authors: C. Gervasio  , E. Grieco  , G. Baldi
Published: July 2017

LaNiO3 and  LaNi0,3Fe0,7O3  have  been  tested  as  catalyst  for  tar cracking  reaction.  They  have  been  prepared,  characterised  and tested  in  a  laboratory  plant  at  500-600°C.  Naphthalene  and  n-exadecane  were  employed  as  representatives  tar  compounds. The  tests  on  LaNiO3  show  that  it  has  a  very  high  activity  but XRD  characterisation  reveals  that  the  catalyst  is  not  stable  in the  reducing  atmosphere  produced  during  the  cracking  tests. XRD and EDS analysis show that there is carbon deposition on catalyst  that  mechanically  blocks  the  passage  of  flow.  The addition of iron in the catalyst structure is effective only for the n-exadecane  cracking  reaction.  In  the  tests  with  naphthalene LaNi0,3Fe0,7O3 does not solve the problem of carbon deposition on catalyst and hence its deactivation.

Authors: B. Verhelst  , J  Desmet  , C. Debruyne  , H. Van Landeghem  , L. Vandevelde
Published: July 2017

Renewable energy becomes more and more
important in our power supply. The aim of this study is to
perform a business economic evaluation of an investment in
photovoltaic (PV) energy. Different cases of PV projects have
been analyzed. In order to have a correct evaluation model,
both economic parameters and technical influences have to be
taken into account. This paper gives an overview and a
sensitivity analysis of the influencing parameters, as well as an
analysis of a practical case. A calculation tool is developed to
allow private persons and companies to determine the
feasibility of an investment in photovoltaic panels. It can be
concluded that not only economic parameters such as discount
rate but also technical parameters have a major impact on the
feasibility of an investment in photovoltaic energy.

Implementation of a New Method for an Improved Voltage Dips Evaluation by the Italian Power Quality Monitoring System in Presence of VT Saturation Effects
Authors: R. Chiumeo  , M. de Nigris  , L. Garbero  , C. Gandolfi  , L. Tenti  , E. Carpaneto
Published: July 2017

The paper deals with a recent measurement
improvement introduced into the Italian power quality monitoring
system, concerning voltage dips detection and their proper
evaluation in the presence of voltage transformer VT saturation
phenomena. Saturation effects, essentially on network operated
with isolated neutral, can give origin to “false” voltage dips, which
can affect the on-line voltage monitoring during a few specific
events (i.e. single line-to-ground faults). The “false dip” problem,
on the other hand, can be considered negligible in compensated
neutral networks.
A new criterion has been developed in cooperation with the
Polytechnic of Turin, based on the detection of a second harmonic
component in the measured voltages, which, once provided with
the proper setting parameters, can succeed in identifying “false”
dips. The criterion effectiveness has been evaluated on field. The
major advantage of the filter implementation in the monitoring
system is that, from now on, network operated with isolated
neutral could be considered quite similar to those operated with
neutral compensation from the point of view of voltage dip
performance.

Authors: JinHong Jeon  , JongYul Kim  , SeulKi Kim
Published: July 2017

This  paper  presents  a  real  time  digital  simulator based   test   system   as   a   new   method   for   testing   microgrid management system (MMS). This system is composed of a real time    digital    simulator    and    a    developed    communication emulator. Real time digital simulator runs a simulation case for microgrid   model   and   distributed   generation   source   model. Communication  module  emulates  communication  functions  of micro-sources   in   microgrid   by   transmitting   the   simulated signals to MMS. The MMS controls operation of micro-sources to  control  the  power  flow  at  the  point  of  common  coupling (PCC) and the voltage and frequency of microgrid. A prototype MMS  was  tested  for  stand-alone  and  grid-connected  operation to  verify  the  validation  of  the  developed  hardware-in-the-loop simulation (HILS) system.
Analysis of unstable phenomenon in TCSC by experiment and simulation
Authors: Hiroki Muramatsu  , Junya Matsuki
Published: July 2017

In this paper, we have investigated damping effect of
power oscillation and unstable phenomena by TCSC
(Thyristor Controlled Series Capacitor) which is one of
FACTS (Flexible AC Transmission Systems) controller.
In this paper, we changed the capacitance of capacitor
in TCSC prototype from 146µF to 73µF to enhance the
damping effect of power oscillation. But we found that
the thyristor in TCSC could not work correctly under
some operating conditions. It is called an unstable
phenomenon of TCSC. So we have examined the
unstable phenomenon by means of both experiment and
simulation.
As a result, we conclude that reducing the capacitance
of capacitor in TCSC is generally effective in damping
oscillation, but we also found that it is necessary to
grasp the region of stable operating conditions where
the TCSC can operate normally.
CUSUM based Fault Detection of Stator Winding Short Circuits in Doubly-Fed Induction Generator based Wind Energy Conversion Systems

Published: July 2017

This  paper  investigates  the  detection  of  short-circuit   faults   in   the   stator   winding   of   a   Wind   Energy Conversion  System  (WECS)  based  on  a Doubly-Fed  Induction Generator  (DFIG).  The  Cumulative  Sum  (CUSUM)  algorithm is  used  to  detect  the  change  in  the  stator  negative-sequence current  magnitude  which  is used  as  the  fault residual.  The  grid voltage  unbalance  is  considered  along  with  the  fault  position and  its  severity  to  evaluate  the  effect  on  the  residual.  The generator  is  modeled  using  the  winding-function  approach. Simulation  results  are  presented  for  a  15  kW  system  operated, under  a  power control strategy, at  rated conditions.  It  is shown that the fault-detection method is able to detect the fault rapidly and  is  not  influenced  by  the  grid  voltage  unbalance  within normal limits.
