采用知识网格技术的智能输电网故障诊断方法

针对现有电网故障诊断专家系统在省级及以上调度中心应用时所存在的诊断速度慢、专家知识在线维护困难等问题,提出基于知识网格技术的智能输电网故障诊断方法。首先将知识网格技术引入智能输电网故障诊断领域;其次结合智能输电网故障诊断的实际应用背景,构建智能输电网故障诊断知识地图,并介绍智能输电网故障诊断知识地图中各个部分的生成方法;最后根据实际案例,对比分析基于专家系统的方法和基于知识网格技术的电网故障诊断方法在诊断效率和知识维护等方面的差异,并指出这2种方法的适用环境。

Novel Fault Diagnosis Approach of Smart Transmission Grid Based on Knowledge Grid Technology

There are some problems in current power grid fault diagnosis system based on expert system such as time-consuming diagnosing and difficulty in on-line expert knowledge maintenance especially in high level dispatching centre. A novel fault diagnosis approach of smart trans- mission grid based on knowledge grid technology was presented for solving problems mentioned above. Firstly, the knowledge grid technology was introduced to smart transmission grid fault diagnosis field. Then the knowledge map of fault d...
