摘要
主要对电力系统电压暂降源的定位方法进行了综述。为了加深对电压暂降源定位问题的认识和理解,从电压暂降的定义、引起原因入手,介绍了电压暂降源定位问题的含义。重点讨论了当前现有的四类主要定位算法,包括基于扰动功率和能量的定位法、基于阻抗实部的定位法、基于暂降分类的定位法及其他方法,并分析了它们各自的原理、优势和不足。在总结目前现有电压暂降源定位方法的基础上,从三个方面对今后的研究工作进行了展望。
Methods for voltage sag source location in power system are reviewed in the paper. In order to understand the problem of voltage sag source location, the paper starts with definition and cause of voltage sags, and introduces the concept of sag source location. Four main methods presently used are discussed emphatically, including the disturbance power and disturbance energy based location method, the resistance sign based location method, sag classification based location method, and other methods. Their principles, advantages and disadvantages are compared. The achievements of all studies are concluded, and three prospects of future work are given in the end.
