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。
Aimed at the problems of slow diagnosis and online maintenance of expert knowledge when existing grid fault diagnosis expert system is applied in provincial and above dispatch centers, a fault diagnosis method based on knowledge grid technology is proposed. Firstly, the knowledge grid technology is introduced into the field of smart grid fault diagnosis. Secondly, based on the practical application background of the fault diagnosis of the smart grid, the fault diagnosis knowledge map of the smart grid is constructed and the methods of generating the various parts of the fault diagnosis knowledge map of the smart grid are introduced Finally, according to the actual case, the differences between the method based on expert system and the grid fault diagnosis method based on knowledge grid technology in diagnosis efficiency and knowledge maintenance are compared and analyzed, and the applicable environment of these two methods is pointed out.
