“…Since the action of a current limiting fuse results in the sudden insertion of a high value resistance, this type of fuse has been modeled as a variable resistance controlled from a TACS section, in which users can specify the parameters that govern the fuse resistance [23]. The input of the minimum melting time-current curve is made by means of a regression equation that matches the characteristic provided by the manufacturer.…”

RESUMENEste artículo presenta las características principales de una librería de módulos desarrollada para representar dispositivos de protección de una red de distribución de energía eléctrica con generación distribuida (GD). El impacto de la generación distribuida depende, entre otros aspectos, del diseño del sistema de protección y de la coordinación entre los diferentes dispositivos de protección. La presencia de unidades generadoras altera el flujo radial inherente a un sistema de distribución y afecta al comportamiento del sistema de protección. Este trabajo presenta una introducción de los sistemas de protección de las redes de distribución y de la interconexión de unidades generadoras, describe la implantación de dispositivos de protección (interruptores, relés, reenganchadores, fusibles, seccionalizadores) en un programa tipo EMTP, y presenta algunos resultados obtenidos mediante simulación, cuyo principal objetivo es ilustrar el impacto que la generación distribuida basada en generadores síncronos puede tener sobre la coordinación de los distintos dispositivos de protección.Palabras clave: Distribución de energía eléctrica, modelación, simulación, generación distribuida, fusible, interruptor automático, relé de sobrecorriente, reenganchador, seccionalizador, protección de la conexión, funcionamiento en isla.

“…The main causes of voltage sag include short circuit fault, starting large induction motors, sudden load variations, and energization of the transformer [7,8]. Voltage sag is a temporary event and its causes are also considered as a temporary low or medium frequency phenomenon [9,10]. Nowadays, with high demands and increases in sensitive equipment, voltage sag is not tolerated in power systems, and various methods have been applied to decrease it [11,12].…”

Abstract:Voltage sag is considered to be the most serious problem of power quality. It is caused by faults in the power system or by the starting of large induction motors. Voltage sag causes about 80% of the power quality problems in power systems. One of the main reasons for voltage sag is short circuit fault, which can be compensated for by a distribution static compensator (DSTATCOM) as an efficient and economical flexible AC transmission system (FACTS) device. In this paper, compensation of this voltage sag using DSTATCOM is reviewed, in which a sliding mode control (SMC) technique is employed. The results of this control system are compared with a P+Resonant control system. It will be shown that this control system is able to compensate the voltage sag over a broader range compared to other common control systems. Simulation results are obtained using PSCAD/EMTDC software and compared to that of a similar method.
