Abstract

Based on the research VSCF doubly-fed wind power systems, it Focus on the line side converter three level. The neutral point clamp in three level converter as line side converter, and it gives its topology structure and equivalent circuit. In PSCAD /EMTDC software environment, the mathematical modeling and system simulation are given, and the simulation results show that the system realized the dc bus voltage stability and can achieve maximum wind tracking.So as to improve the quality of the output waveform and the utilization rate of wind power generation system.
