摘要/Abstract

摘要： 我国风电以集中接入、远距离输送为主要开发方式，随着风电并网容量快速增长，风电运行事故也呈现上升的态势，特别是近年，已发生多起连锁脱网事故。以某典型风电汇集系统发生的连锁脱网事故为研究案例，从系统网架结构、设备性能、运行方式、无功电压控制等因素着手，系统地分析它们对连锁脱网事故的影响，及相互递进关系，分析结果对于风电汇集系统连锁脱网研究和防范具有参考意义。

Abstract: Cascading wind turbine trip-off accidents occurred frequently in north China recently. A detailed analysis is performed on one typical case happened in practical centralized wind farm to reveal the accident reason and evolution process. The four major impacting factors during the accident, namely network structure, equipment characteristics, operation mode and reactive voltage control, are analyzed systematically. The analysis results, along with corresponding countermeasures, provide suggestions for future wind farm cluster practice.

Key words: wind farm cluster, cascading trip-off, voltage sensitivity
