Grid Fault Ride Through Capability of Voltage Controlled Inverters for Photovoltaic Applications
Authors: Islam Abdelraouf  , Sobhy Abdelkader  , Mohamed Saeed  
Published: September 2020

Fault ride through (FRT) capability is one of the challenges faced in today's large-scale grid photovoltaic (PV) power system.
Solar PV systems are designed to disconnect, and remain offline for 5 mints when tripped by loss of grid voltage. However, The PV system, by itself, cannot differentiate between transient and sustained grid voltage loss. It behaves in the same manner in the two cases, i.e., disconnect, stay offline for five minutes and then makes re-connection trial. Staying offline for fiveminutes unnecessarily wastes considerable amount of clean energy from the PV, may affect the power balance of the grid and many other adverse effects of service discontinuity.
This paper presents a new control strategy for grid FRT capability of a large grid connected PV System to increase the stability and reliability of the PV system, in which a photovoltaic inverter can be controlled to pass transient faults. Our strategy is to control the inverter so that it disconnects from the grid when the current exceeds a specific value for a specific time otherwise, it still connected and ride-through the faults to ensure continuous output power under transient fault conditions. A case study of a 100 KW PV power system simulated to ensure the proposed control. The results show the ability of the proposed control method to manage various types of grid faults.

Tolerance of Three Deep South Non-turf Ornamental Groundcovers to Applications of Postemergence Herbicides1
Authors: Marble S. Christopher , Pickens Jeremy M. 
Published: September 2020

AbstractOrnamental groundcovers are a popular alternative to turfgrass in landscapes due to their low maintenance requirements, pest resistance, and shade tolerance. Weed control is a challenge in these groundcovers because few herbicide options are available. The objective of this research was to determine the tolerance of the groundcovers Asiatic jasmine [Trachelospermum asiaticum (Nakai) ‘Minima'], perennial peanut [Arachis pintoi (Krapov.& W.C. Greg.) ‘Golden Glory'] and dwarf mondo grass [Ophiopogon japonicus (L.f.) Ker Gawl.] ‘Nana'] to herbicides, including bentazon, clopyralid, fluazifop-P-butyl, glufosinate, halosulfuron, imazaquin, sethoxydim, sulfentrazone, and sulfosulfuron applied at approximately 2 times the label rate. Asiatic jasmine and perennial peanut were evaluated in Apopka, FL and dwarf mondo grass was evaluated in Mobile, AL. Bentazon, clopyralid, glufosinate, glyphosate, and sulfosulfuron caused unacceptable injury and/or a reduction in shoot growth for all three species while fluazifop-P-butyl and sethoxydim caused no injury to any species. Halosulfuron caused minor injury but significantly reduced growth of dwarf mondo grass. Sulfentrazone caused no injury to Asiatic jasmine or perennial peanut but caused severe injury to dwarf mondo grass after only one application. Similarly, imazaquin caused only minor injury to Asiatic jasmine and dwarf mondo grass but significantly reduced growth of perennial peanut after two applications.Index words: Postemergence herbicides, groundcovers, mondo grass, perennial peanut, Asiatic jasmine.Chemicals used in this study: Bentazon (Basagran® T/O), 3-(1-methylethyl)-1H-2, 1,3-benzothiadiazin-4(3H)-one 2,2-dioxide, clopyralid (Lontrel), 3,6-dichloro-2pyridinecarboxylic acid, fluazifop-P-butyl (Fusilade® II), (2R)-2-[4-[[5-(trifluoromethyl)-2-pyridinyl]oxy]phenoxy]propanoic acid, Glufosinate (Finale®), 2-amino-4-(hydroxymethylphosphinyl)butanoic acid, Glyphosate (Ranger® PRO), N-phosphonomethyl)glycine, Halosulfuron-methyl (SedgeHammer®), methyl 3-chloro-5-[[[[4,6-dimethoxy-2-pyrimidinyl)amino]carbonyl]amino]sulfonyl]-1-methyl-1H-pyrazole-4-carboxylate, Imazaquin (Sceptor® T&O), 2-[4,5-dihydro-4-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl]-3-quinolinecarboxylic acid, Sethoxydim (Sethoxydim SPC), 2-[1-ethoxyimino)butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one, Sulfentrazone (Dismiss®), N-[2,4-dichloro-5-[4-difluoromethyl)-4,5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol-1-yl]phenyl]methanesulfonamide, Sulfosulfuron (Certainty®), 1-(4,6-dimethoxypyrimidin-2-yl)-3-[(2-ethanesulfonyl-imidazo[1,2-a]pyridine-3-yl]sulfonylurea.Species used in this study: Asiatic jasmine ‘Minima' (Trachelospermum asiaticum ‘Minima'), perennial peanut (Arachis pintoi ‘Golden Glory'), dwarf mondo grass (Ophiopogon japonicus ‘Nana').

El tratamiento de la oratoria sagrada en la "Historia del famoso predicador Fray Gerundio de Campazas"
Authors: Celma María Pilar 
Published: September 2020

La lectura tradicional de la HFGC suele reducirse al análisis de la dimensión paródica de este libro. Para valorar si la propuesta del padre Isla era el medio más efectivo de crregir los excesos de la predicación, conviene analizar la realidad extratextual que da origen a la sátira, atendiendo a las causas de la decadencia de la oratoria sagrada, a las soluciones que en el momento se sugieren, y a la postura del propio Isla, quien -antes ya de la HFGC- había ensayado las posibilidades de la sátira en un opúsculo prácticamente ignorado por la crítica. Pero el P. Isla no busca sólo la parodia, sino que, con la HFGC, construye una obra de la que emerge una propuesta muy seria de reforma de la predicación. En este sentido, el P. Isla aborda el análisis del "modus concionandi" desde tres frentes: el diagnóstico de la situación real; la censura de obras concretas, de carácter preceptivo o ejemplar; y la teorización -en boca de personajes graves- sobre lo que debería ser la predicación: toda una retórica implícita, que la lectura aquí propuesta pretende explicitar.
Convergencia y oficio entre Baltasar Lobo y Claudio Rodríguez (la alegría, el impulso y el vuelo)
Authors: Ramos de la Torre Luis 
Published: September 2020

En este artículo se trata de comprobar la cercanía y la convergencia que se produce entre la escultura de Baltasar Lobo y los versos de Claudio Rodríguez a partir de algunos conceptos esenciales: amor, moralidad, mejora, paisaje, materia, impulso, maternidad, casa, amistad, alegría… Aspectos que definen la obra y el oficio de estos dos creadores, en los que la presencia de la luz de las tierras zamoranas y el primer paisaje humano que vivieron serán algunas de las claves fundamentales para definir su modo de ver y de asumir lo artístico. Con ello, se pretende aclarar las principales preocupaciones artísticas que rodean la cosmovisión y el oficio de cada cual, así como las líneas que definen las pautas a seguir en sus obras respectivas, ya sea desde el punto de vista del arte o desde la poesía. Líneas de acción creativa y conceptos que, a su vez, pueden dar lugar a la constatación de un mundo de convergencias y cercanías conceptuales, tanto de emoción como de motivación y creación, entre estos dos paisanos.
De igual modo, se analizan otros aspectos como: la complementación de la levedad y la ingravidez presentes en su obra artística con la pesantez de la materia ofrecida al oficio de cada uno de ellos; la visión de dicha materia como algo sagrado y salvador; o la importancia crucial de la moralidad presente en su cosmovisión y en sus obras. Claves que les llevan a pensar en el creador y en su oficio dentro siempre de una tarea definida por la búsqueda de la mejora del hombre en todos los sentidos.
