摘要
为解决故障信息数据庞大、信息不确定性以及故障诊断算法的选择性等问题,本文依据IEC61970的公共信息模型(CIM)以及IEC61968的CIM扩展模型,搭建故障诊断信息统一模型,并在扩展故障信息模型的基础上,提出基于拓扑搜索的配电网故障诊断算法。该算法是在故障发生后,诊断程序调用以CIM为模型的配电网拓扑结构及故障信息数据,采用简单的深度优先搜索方法实现故障诊断。文中给出实现算法的流程图,并用某配电网局部联接图验证该算法的正确性,结果表明本文提出的故障诊断算法具有一定的可行性和准确性。
To deal with abundance and uncertainty of fault information data,and the choice of diagnostic algorithms,a unified information model for fault diagnosis according to IEC61970 common information model（CIM） and IEC61968 extended CIM is built in this paper.Therefore,a fault diagnosis method for distribution network is put forward based on topology search.If fault occurs,fault detection program calls for distribution network topology and fault information of the CIM,and the fault can be diagnosed by simple depth-first search method.In this paper,flow chart of algorithm is given,and the correctness of the algorithm is verified by using of a local connection diagram for distribution network.Calculation results show that this algorithm is feasible and accurate.
