Diseño de esquemas de control integrado de tensión y potencia reactiva del sistema de distribución de la Empresa Eléctrica Regional Centro Sur C. A.

Abstract

This work resents an alternative optimization schemes applied voltage for the integrated voltage control and reactive power (IVVC -Integrated Volt / VAR Control) under the concept of CVR (Conservation Voltage Reduction), in order to manage demand and increase energy efficiency in the distribution system feeders of CENTROSUR. Evaluated the potential benefits of this initiative are: energy saving, reducing the cost of capacity, reduction of CO2 emissions to the environment and loss reduction.

A methodological guide for the preparation of information (construction of energy profiles of measuring points and load model), selection of candidates feeders (base case analysis) to quantify the benefits is proposed; supported by the software tool CYME. This analysis is to evaluate the voltage profile in each of the nodes of a feeder for the period of one year. The goal is to strategically place equipment regulation and control (voltage regulators and capacitor banks) to get flatten the profile and move within the ranges allowed by the CONELEC voltage regulator. This reduction scenarios voltage of 1 %, 2 %, 3 % and 4% in head, to quantify these benefits and get the CVR factor are evaluated.
