Considerations regarding the Control of a Mixed Genset based on the usage of Synchronous and Asynchronous Generator

摘要

This paper proposed a voltage and frequency control algorithm of a mixed group based on the usage of synchronous and asynchronous generator. The control algorithm involves the presence of three control loops that implement for the synchronous generator - the excitation and torque control, and for the asynchronous generator - the torque control. In the paper is used the orthogonal model for the both two generators. The usage of wind energy and of the water accumulations with variable flow imposed the asynchronous generator beside the synchronous one in nowadays energy power systems. There are conducted simulation studies regarding the gensets (synchronous and asynchronous generator) behavior under several load variations. The conclusions prove and validate the solution of using of mixed gensets within the electric energy power networks.
