Minimization of output fluctuation of a fixed speed IG based wind farm without capacitor by using PMSG

Abstract

Capacitors are considered as the prime element in a fixed speed Induction Generator (IG) based wind farm along with the other external controlling devices for providing the necessary reactive power compensation. But this paper proposes that the capacitors as well as the external controlling devices can be eliminated from the wind farm if Permanent Magnet Synchronous Generator (PMSG) is included in the system. The proposed model of PMSG works not only as a power producing generator but also as a controlling device for IG. A 50 MW wind farm has been considered for this study which consists of both IG and PMSG without any capacitors or controlling devices. Varying load condition has also been considered for a composite wind farm with Synchronous Generator (SG). Simulation results prove the effectiveness of the proposed system. Both the dynamic and transient analyses have been carried out by using the laboratory standard power system software package, PSCAD/EMTDC.
