Afundamento de tensão de geradores síncronos devido à partida de motores de indução trifásicos, usando o software PSP-UFU

Abstract

Currently, electrical appliances are increasingly common in generators and electrical appliances, as they have an efficient capacity for a better driving force in electrical appliances. Among these electric motors, the most used, both in Brazil and abroad, are three-phase induction motors. In this work, research was carried out on the voltage fundamentals of synchronous generators due to the depth of three-phase motors, to demonstrate whether the starting models were following current standards, different case studies. So, it was necessary to analyze an industrial system with the independent synchronous generation, which was adapted by the literature and implemented computationally through the PSP-UFU software. Faced with some electrical devices such as generator terminals were not considered to classify voltage electrical devices such as voltage generators. These facts proved to be in one of the case studies when more than one induction motor started on the same bus as well as when all induction motors of the industrial system started simultaneously. Finally, different solutions were presented in the literature to attenuate these stress phenomena.
