摘要
将模糊集合理论中模糊隶属度的概念应用到电力系统振荡与短路的识别中 ,通过提取恰当的特征量并赋以一定的权值 ,对短路、振荡及振荡伴随短路这三种情况进行综合判断。仿真分析结果证明该方法的效果是非常明显的 。
This paper introduces the concept of fuzzy set theory into the discrimination between faults and power swings. By means of abstracting the proper characteristic parameters and endowing them with the proper weights, we can easily make comprehensive estimation on the three conditions: faults, swings and faults in swings. It is obvious that this method is highly effective from the result of much simulation.
