The Analysis on Voltage Stability of Power System Including Different Wind Generator

Article Preview

Abstract:

Output power characteristic of wind generator has different influence on PCC voltage stability, which consists of three kinds wind generator- constant speed induction wind generator, doubly-fed variable speed constant frequency (VSCF) wind generator(DFIG), and direct-driven permanent magnetic synchronous generator ( PMSG).This article establishes simulation model of power grid interconnected by wind farm under Matlab environment, and writes flow calculation procedures. The simulation results show that doubly-fed VSCF wind generator and direct-driven PMSG can improve PCC voltage stability when the fault happened in wind power grid integration.
