考虑容错的配电自动化主站故障定位方法

Fault Location Method for Master Station of Distribution Automation Considering Fault Tolerance

摘要:

为避免配电线路故障指示器信号不健全时配电自动化主站故障判定方法失效,从容错的角度对主站定位方法进行了探索。首先分析了故障指示器故障时上报的遥测、遥信等多种信息的特点,提出了上报信息对应的故障决策表,再根据不同的决策表得到初始的故障定位结果,然后通过加性策略对初始的定位结果进行融合,得到最终的故障定位结果。最后通过算例分析,该方法适用于信息漏报和误报的情况,且能获得更加可信的定位结果,为配电自动化主站的故障定位提供一种新的思路。

Abstract:

In order to avoid the failure of fault determination method for master station of distribution automation when the fault indicator signal of distribution line is not perfect，the fault location method of master station from the perspective of fault tolerance is explored． Firstly the characteristics of telemetry intelligence，remote signals and other information reported by the fault indicator when the fault occurs are analyzed，and fault decision table corresponding of different reporting information is proposed． The result of the initial fault location is obtained through the decision table，and then the initial positioning result is combined with the additive strategy to obtain the final fault location result． Finally through case analysis，the proposed method is suitable for the information omission and false positives，and can obtain more reliable positioning results，which provides a new idea for fault location method of master station of distribution automation．
