摘要

对一个双馈型风电机群在近满载状态下发生的连锁脱网事件进行了分析，揭示了这类风电机群连锁脱网的机理，分析了风电机组运行状态、电网电压陷落扰动、风电机组Crowbar保护定值等因素在连锁脱网中的作用，提出了降低此类连锁脱网风险的技术措施建议。仿真结果说明了分析方法和抑制措施的有效性。

Abstract

A cascading trip-off of doubly-fed induction generators from grid in a wind turbine clusters has been analyzed in this paper. The cascading trip-off mechanism is investigated. Relevant factors to the cascading trip-off are analyzed， such as operational state of doubly-fed induction generator， value of voltage dip， Crowbar protective setting value of doubly-fed induction generator and so on. Technical measurements for reducing the risk of cascading trip-off are presented. Simulation results show the effectiveness of the above analysis and measurements.
