双馈型风电机组的Crowbar仿真研究

Study of Doubly-fed Type Wind Turbines Crowbar Simulation

耗能电阻具有成本低,结构简单等优点,使其成为风电机组低电压穿越的组成部分。本文通过PSCAD仿真软件对双馈型风电机组的Crowbar保护电路进行了仿真研究。仿真结果表明Crowbar保护电阻使风电机组在低电压穿越期间能够快速的恢复到正常的运行范围内。

Crowbar with low cost and simple structure advantages make it becoming the component of doubly fed induction generator during low voltage ride through. Based on PSCAD simulation software, Crowbar protection circuit of doubly fed induction generator was simulated. The simulation results show that Crowbar can make the doubly fed induction generator quickly return to normal operating range in the low voltage ride through periods.
