摘要
提出了电力系统故障定位的重要性,选用一种原理简单,动作可靠的故障选相算法,在此基础上,综合多种定位算法的优点,结合故障分析系统的实际情况,采用阻抗法实现故障测距,并利用故障分量电流来消除过渡电阻的影响。
This paper points out the importance of faults location in power system. It selects an algorithm of fault phase selection with simple principle and reliable operation. Qn this basis it synthesizes advantages of many location algorithms. Combining with the present situation of fault analysis system, it adopts resistance method to realize fault location, and uses fault branch current to eliminate the influence of transition resistance.
