农村配电网故障定位方法的研究

文章提出了运用粗糙集理论实现农村配电网故障定位的方法。该方法根据配电网拓扑结构利用各用户区故障投诉信息作为条件属性、故障元件作为决策属性,形成故障决策表,并以此决策表为主要工具,然后利用粗糙集方法对决策表进行属性约简和值约简,导出故障决策表的最小约简形式,获得最小诊断规则,保证了规则的客观性,而且在故障投诉电话信息不完备的情况下,仍能达到快速、准确故障定位的目的,具有良好的容错性能。算例表明该方法简单、可行、有效。

Research on the Fault Location Method of Rural Power Distribution Network

The rough set theory is used to realize the automatic fault location method of the rural power distribution network.According to the distribution network topology,this method uses each user area fault complain information as condition attribute,uses fault component as decision attribute,forms decision table,and uses the decision table as the main tool,then uses rough set method to perform the attribute reduction and value reduction.The minimum fault reduction form is derived to ensure objectivity of the rul...
