Desarrollo de un módulo informático para el cálculo del nivel de carga de transformadores de distribución de uso residencial considerando cocinas de inducción

Abstract

The impact of the incorporation of induction cookers in transformers, in the service area of Empresa Electrica Quito, is analyzed through a computer module that calculates the load level of the transformers of residential use on the basis of the Geographic Information System (GIS) of EEQ. The module calculates the load level at peak hours at midday and at night in three scenarios: considering induction cookers installed, considering a progressive inclusion of kitchens based on the Efficient Cooking Program (PEC) record and a simulation of one kitchen per user, for this, the EEQ commercial system database (SIEEQ and PEC) and the technical losses department (PRPT) are used. In addition, a part of the module simulates a redistribution of load between two transformers in order to improve the load level in them. The module is applied in the primary "D" Andalucia (17), with previous field inspection and updating of the information, as a result, as a result of the simulation of an induction cooker by user, an increase of 33 transformers (out of a total of 79) is evidenced, would have a load level greater than 130%, ie they would be overloaded. In addition, it is concluded that the maximum demand considering induction cookers, low consumption commercial and artisan industrial, is given at midday.
