Atenuação do afundamento de tensão em geradores síncronos isolados quando submetidos a partida direta de motores de indução

Abstract

This work presents a proposal based on controlled switching capacitors at the time of direct start of induction motors when they are energy supplied by synchronous generators isolated. This procedure enables mitigate or even eliminate the sag that occurs during this transitional period. Allowing a smoother start condition of the engine, when viewed by the synchronous generator. To validate the proposal, will be issued the results obtained through computer simulations, with the achieved in practical experiments. After these analyzes, it will be shown that the proposal can be applied for generator sets, that when supplying motor loads have their design made based on starting such machines. May lead to one on generator set sizing, cause various problems for its operation.
