Published: December 2020

Abstract
With the rapid development of UHV DC transmission, there is an increasing demand for the construction of AC/DC hybrid systems. Because the AC/DC hybrid system requires high system stability on the AC side, an intelligent reclosing strategy is needed to ensure that the line will not reclose after a permanent fault occurs. Based on the traditional voltage criterion, this paper has proposed a new discriminant that can stably distinguish the fault type to reduce the error judgment range, maintain the stability of the power system and ensure the safe and continuous operation. This paper also did a simulate with the RTDS (Real-time Simulation System) to verify the accuracy and reliability of the new discriminant.

Published: December 2020

Abstract
With the continuing advance of electricity market reforms, China is currently in the transition stage from a dual-track electricity price system to a market-based single-track system. The new electricity price system, which is based on market transaction electricity prices and transmission and distribution prices; and the original electricity price system, which is based on the feed-in tariffs price and catalog electricity prices, are dual-track operation. Based on the evolution path of China’s macro development, this paper clarifies the connotation and settlement mechanism of China’s dual-track electricity price system and discusses the differences and connections between the dual-track system settlement, planned settlement, and market-based settlement. Then, by adopting an adjusted Computable General Equilibrium (CGE) model, this paper quantitatively evaluates the economic and social benefits of the dual-track electricity price system. Based on these results, this paper further analyses the subsequent challenges and countermeasures of the transition from the dual-track electricity price system to the market-oriented price system.

Published: December 2020

Abstract
Photovoltaic(PV) power forecasting is of great significance to improve the access level of photovoltaic power generation. Deterministic forecasting methods often fail to meet the needs of grid risk analysis and decision-making, and a single model is also difficult to adapt to the changes of PV objects under different meteorological conditions. In order to solve the above problems, this paper describes the seasonal distribution characteristics of PV output fluctuations, and a method of PV power uncertainty forecasting based on seasonal classification is proposed. Compared with the parameter estimation method, the nonparametric kernel density estimation method does not need to make assumptions about the distribution of the prediction error, and can obtain more information about the actual distribution of the error, and has no fixed requirements for the various distribution characteristics of the error, it has strong adaptability.

Authors: Zhang Yongzhuang , Wang Jingfu 
Published: December 2020

Abstract
When the wet flue gas of a gas power plant is discharged, a white wet plume of flue gas will be produced, causing environmental and visual pollution. Local governments require the treatment of white wet Plume of flue gas. This paper establishes a model of the process of flue gas emission to produce white wet plume of flue gas, and the numerical method is used to solve it. The effects of factors such as flue gas emission temperature and flue gas moisture content on the generation of white wet plume of flue gas are studied respectively. The results show that the numerical simulation method has a good simulation effect for studying the generation conditions and factors of the white wet Plume of flue gas. It is possible to obtain the limit emission temperature and the emission moisture content of the flue gas emission without producing white wet Plume of flue gas. It is possible to study the generation of white wet plume of flue gas under the conditions of different flue gas emission temperature and emission moisture content, and provide reference and guidance for the engineering practice of power plant flue gas reduction or elimination of white wet plume of flue gas.

Abstract
The clarification of the dry matter accumulation, distribution law and yield differences of silage corn under different nitrogen application rates will provide theoretical basis for determining the optimal nitrogen application rates of silage corn under drip irrigation in central Inner Mongolia. In this study, Zhongxing silage 1 was selected as the experimental variety. This paper systematically analyzes the dry and fresh weight accumulation and growth rate, dry matter distribution and yield index of silage corn in the whole growth period under the condition of six different nitrogen application amount in two consecutive years of 2018 and 2019. The results indicated that the application of nitrogen fertilizer increased the whole plant fresh weight and dry matter content in different growth stages after the seedling stage of silage corn, and the whole growth period from the seedling stage to the harvest stage, the fresh weight and dry matter accumulation rate of N16 and N20 treated plant were higher than other treatments in 2018 and 2019. Except for the leaves at the trumpet period, the dry matter distribution ratio of each organ was not affected by nitrogen application level before tasseling stage. In the silage harvest period, the biological fresh weight and biomass yield of silage corn were the highest in N16. It can be concluded that N16 (240kg N ha−1) is the best nitrogen application rate for silage corn under drip irrigation in central Inner Mongolia by means of comprehensively comparing the dry matter accumulation rate, distribution and yield under different nitrogen rates.
Research on method for detection of harmful gases in livestock based on open path laser absorption spectrum
Authors: Tian An , Dong Daming , Ji Zengtao , Jiao Leizi 
Published: December 2020

Abstract
The breath and feces of livestock and poultry will produce harmful gases such as ammonia, hydrogen sulfide and carbon dioxide. When the concentration of these gases exceeds the standard, they will seriously harm the health of livestock and poultry and even keepers. Fast and accurate monitoring of these harmful gases is of great significance in improving the health status of animals and keepers. Laser spectroscopy technology is an effective means of gas detection. Because of its high sensitivity and selectivity, it is widely used in gas monitoring. However, the currently adopted method of pumping sample gas detection based on the long optical path gas absorption cell is susceptible to the influence of the high ash and high humidity environment of the livestock and poultry house, causing detection errors. Open path laser absorption spectroscopy technology does not require a gas absorption cell to detect the gas concentration in free space. Based on this principle, this paper develops out the research on the open path laser absorption spectroscopy detection method for harmful gases in livestock and poultry houses, focusing on the design of laser collimation system, laser reflection system, laser focusing system, and laser detection system. The ammonia gas was used as the detection object to verify the feasibility of detecting harmful gas in livestock and poultry houses with open path laser absorption spectroscopy.

Published: December 2020

Abstract
The quality of Shanxi aged vinegar (SAV), a famous Chinese vinegar, was improved during its special long-time ageing. SAV samples of different ageing time were analyzed by composition analysis, rheometer, and principal component analysis (PCA). Three main quality indicators of SAV, namely total acidity, soluble solids content and R ratio, and most of composition, including glucose, acetic acid, lactic acid and total polyphenols increased when ageing process prolonged. Newton function and Power law model were fitted to rheological data to investigate the rheological characters: shear viscosity, consistency coefficients and flow behavior index (n). PCA showed the viscosity of SAV had positive relationship with ageing time as well as all composition parameters. Quality including main quality indicators, composition and rheological characters was significantly differenct (p < 0.05) among the SAV in different phases. Thus, the rheological method was a very useful tool to classify the quality of SAV.

Abstract
In recent years, our country (China) has invested more and more in environmental protection, and resource recycling concept is also gaining in popularity. The free throw of the peel wastes both increases the load on the environment and wastes the useful ingredients in the peel. It is a natural pigment anthocyanin, not only has the natural colorants function but also has a high biological value and medicinal value. Useful anthocyanin extracted from the peel waste is a manifestation of the principle of “turning waste into treasure and utilization”. The Surfactant precipitation technique is a relatively new plant anthocyanin extraction method. Anionic surfactant-sodium dodecyl sulfate was selected to experiment, and the extraction efficiency of sodium dodecyl sulfate precipitation technique peel waste anthocyanin was discussed. Parameters such as surfactants, potassium chloride, sodium chloride concentration pH, and other factors on the recovery of the solvent category extraction affect the results. The results showed that optimal experimental conditions for 3mL crude extract solution, as follows: pH is 2, using 4mL5mmol/L of SDS, 1.5mL 6mmol/L of KCl,1mL AR acetone, 1mL 0.25mol/L of NaCl, under the best condition, the rate of anthocyanin extraction was up to 60.81%.

Published: December 2020

Abstract
The influences of different ammonia-nitrogen molar ratios (Normalized Stoichiometric Ratio, NSR) on the NOx emission concentration, ammonia escaping amount, and selective non-catalytic reduction (SNCR) denitrification efficiency were measured through a field test. The results show that with the increase of NSR, the NOx emission concentration changes little, the ammonia escaping amount is gradually increased, and the SNCR denitrification efficiency is basically kept stable after increasing firstly. In full consideration of the ultralow emission limit and reducing agent consumption, it is believed that 2.01 is the optimal NSR value under the test load.

Published: December 2020

Abstract
A study was carried out at a subtropical zone of southern west China to test if hyperspectral methods could be used to measure turf canopy chlorophyll concentration, and to analyse correlation between green normalized difference vegetation index (GNDVI) values. Turf chlorophyll concentration, canopy hyperspectral reflectance, and visual rating were measured. The results showed that canopy hyperspectral reflectance value was more sensitive to the turfgrass chlorophyll concentration difference than visual rating both among turfgrass species. Visual rating value and hyperspectral index were both highly correlated with canopy chlorophyll concentration. Regression analysis indicated a strong linear correlation between GNDV and visual rating value. Hyperspectral technique can provide an improved method to evaluate turfgrass chlorophyll concentration and to quantify turfgrass color.

Authors: Solovitskiy A N , Nikulin N Yu , Nastavko A V , Smirnov N A , Makarov K A 
Published: December 2020

Abstract
It has been established that the problem of using applied low-depth geophysical technologies to ensure the sustainability of industrial and civil construction in Kuzbass is as follows: on the one hand, there is a significant increase in measurement accuracy and efficiency, and on the other hand, there is the absence of new models that allow interpretation of not only base soils and geological objects, but also their condition. The research provides a generalization of practical experience in creating physical and geological models. Based on the studies, it was found that applied shallow geophysical technologies are more informative and automated than traditional ones. The practical use of this theory is to ensure the sustainability of industrial and civil construction, and, consequently, the development of the Kuzbass territory.

Published: December 2020

Abstract
Distributed Generation (DG) is a global trend and it is actively spreading in Russia. In contrast to Western countries, the main incentive for the spread of DG in Russia is the desire of industrial owners to reduce the final cost of electricity. DG in Russia can successfully meet the challenge of supplying electricity to isolated and inaccessible areas and replacing outdated and inefficient generation. The widespread use of DG, including those based on renewable energy sources (RES) makes it necessary to create promising models for the inclusion of DG in the Unified Energy System (UES) of Russia. The paper deals with the efficiency of DG, analyses the application of this technology in Russia formulates the prospects for the development of DG in Russia and gives recommendations for the integration of DG.
