利用系统辨识进行超前预测中止的在线快速仿真法

Fast on line simulation method based on system identification

应用基于系统辨识的快速暂稳预测方法 ,超前判别系统的稳定性及稳定裕度 ,在充分保证判断准确性的情况下 ,对某些可以确认为稳定的故障 ,超前中止仿真计算 ,从而大大节省在线动态安全分析的宝贵时间 。

A new method of fast predicating system stability based on system identification is presented in this paper.By means of distinguishing the stability margin of power system,stability simulation can be terminated in advance.Therefore,it is possible to realize on line quasi realtime stability control.
