风电场低电压穿越和短路电流仿真与分析

Simulation and Analysis on Low Voltage Ride through Capability and Short Circuit Current in Wind Farm

随着风电规模的不断发展,在故障情况下接入电网的风电机组正常运行影响着电网的安全稳定。运用PSCAD仿真分析软件,采用某一地区实际电网模型对风电场低电压穿越及其对故障点短路电流的影响进行分析,得到电网故障时风电场的低电压穿越特性与短路电流间的关系。

With the development of the scale of wind power,the normal operation of wind turbines for the security and stability of power grid is essential,in the case of grid failure. Based on PSCAD simulation software,this paper analyze the wind farm of low voltage ride through capability and short circuit current,getting the relationship between the low voltage ride through capability and short circuit current.
