Transient Stability Analysis Method for Wind Power Generation with using Induction Generators

风电机组暂态稳定评估是电力系统安全运行的主要问题之一。风力发电机组的暂态稳定性由其对应的临界清除时间(CCT)决定。传统上，感应发电机CCT的确定涉及大量的试验和误差方法，其需要相关的时域模拟的重复运行。本文介绍了风力发电系统中的感应发电机在三相故障情况下的暂态稳定分析技术。该方法节省了相关时间域仿真的重复运行时间。利用MatLab/Simulink进行试错法的计算结果验证了该方法的有效性。

Transient stability assessment of wind power generator is one of main issues in power system security and operation. The transient stability for the wind power generator is determined by its corresponding critical clearing time (CCT). Conventionally, determination of the induction generator CCT involves a large number of trial and error methods that requires repetitive runs of related time domain simulation. In this paper, we present transient stability analysis technique for induction generator used in wind power generating system at three-phase fault conditions. The proposed method saves time in consuming the repetitive runs of related time domain simulation. The validity of the developed technique is confirmed by the results obtained from trial and error method using Matlab/Simulink.
