Estudio de reguladores para mantener el nivel de voltaje en un rango de operación que demanda la carga (13.2KV) como mínimo y máximo (13.8KV) a la alimentadora (Interagua-San Juan)

Abstract

Population expansion and new business installations cause additional downstream loads on distribution lines, generating a significant impact on various aspects of the electric power system, and it is essential that system planners and operators adequately manage these loads to guarantee a safe, reliable and efficient electricity supply. The analysis involves the urgent need to address overvoltage problems in the Interagua feeder, which has a route of 9,12km and 0,3km with three-phase 4/0 AWG ACAR cables (Ø 13,23mm) and a 1/0 AWG neutral (Ø 9,36mm); This feeder is located in the province of Guayas in the Juan Gómez Rendon parish also known as Progreso; The growing demand at S/E San Lorenzo del Mate has generated the need for technical and operational solutions to efficiently manage loads and guarantee voltage stability, thus avoiding interruptions of the service of this or other companies. By collecting data through the National Electricity Corporation (CNEL), the single-line diagram is created in Etap from the connection point at the Posorja-Transelectric Substation to the San Lorenzo del Mate Substation, with the aim of realizing the flow of power that allows me to visualize the behavior of the voltage in its 4 feeders with their respective maximum loads, once the power flow has been carried out and the overvoltage problem has been verified, the sizing of the regulator bank is carried out. Depending on the capacity in KVA, the regulator bank is selected by consulting the corresponding catalog. Likewise, the simulation is run with the regulator bank in Etap (Voltage Regulator) with the purpose of reducing the voltage levels in the Interagua feeder.
