摘要
在Matlab/Simulink中建立了包含双馈式异步机风电场的单机无穷大电力系统仿真模型。通过仿真,对各种故障状态下的风电故障电压、电流进行分析,得出风电场在电网各种故障状态下的短路电压、电流特性是不同的,因而得出风电场保护应采用适应性保护配置,并对保护原理和整定方法进行了说明。
The power system tie-line that the wind power generation sets were connected to single infinitive bus system occurred short circuit fault,which was set up in Matlab/Simulink to dynamic simulation.Through DFIG fault voltage and current curve of different fault types,it reached to conclusion that wind farm should apply adaptive relaying for the protection,and then a describtion of the protecting principles and setting method was given.
