Study of Fault Location by Rough Sets Based on WEBGIS for Distribution Network
Zhao Qing-song · Automation and Instrumentation · 2006
A newly reduced algorithm based on RS theory is proposed for fault location with WEBGIS environment by using the information of trouble calls from different positions.For a given structure of a certain distribution network,first,the decision table including all kinds of fault cases is established as the main tool.Then,using the new algorithm,fault location rules are extracted by reducing the decision table.The reduced result can be synthesized into one as a tabulated expert decision library.Furthermore,the reduced result can discover the inherent redundancy of trouble calls information set.Finally,a practical fault location program is proposed based on C# program language with the main interface made by WEBGIS.By making the best of the corporate network data source,the program makes the operation of fault location easy and effective,then realize the visualization of fault location.Sufficient simulation to the actual distribution networks show that the method is feasibile and efficient.
