Energy diagnosis of the electrical supply system of the Technical University of Cotopaxi

Abstract

Currently, the planning deficit in load distribution, added to the accelerated growth of electrical demand at the Technical University of Cotopaxi (UTC), has caused a load imbalance between the phases, being outside the limits established by the standard. 004-01 CONELEC. This project is aimed at the energy diagnosis of the electrical system in block A and B. To solve this problem, measurements were carried out with the Fluke 435 series II network analyzer on the main boards, acquiring the electrical variables of the entire system. , and with the help of the electrical plans, a survey of all the installed load necessary for the simulation of power flows was carried out. The simulation was carried out with the use of ETAP 12.6.0 software, which allowed obtaining the voltage and current drop rates of each phase. It was possible to demonstrate that the new loads incorporated into the system were carried out without a prior study, resulting in a phase imbalance, which causes a current through the neutral that deteriorates the equipment and reduces its useful life. The scope of the diagnosis includes establishing strategies for technical solutions in the existing critical areas.
