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