摘要
Abstract
Two mathematical models of DFIG under the healthy and faulty with Stator Winding Inter-turn Short Circuit ( SWITSC) condition respectively were developed. Then combined the wind turbine drive train model and pitch control system for the small-signal stability studies. Changed the external conditions and internal state( such as wind speed and short circuit ratio varied ) , infering whether the DFIG wind power system was stable by Lyapunov stability theory, then observe the eigenvalue loci. To analyze the impact parameters, introduced the participation factors. The computer simulations were applied to validate the conclusions. The results showed that the effect of SWITSC fault to DFIG wind power system could be accepted within a certain range.关键词
