摘　　要：针对现有电网故障诊断模型存在的诊断性能低、模型不完备等问题,构建一种面向电网故障诊断的分层免疫模型。首先,分析固有、适应性免疫的防御作用及配合关系;然后,探讨电网故障诊断系统面临的主要问题和设计要求,提出相应的技术思路;最后,参照免疫系统的有关原理与防御机制,采取分层诊断策略,构建一种能够适用于电网故障诊断的分层免疫模型,介绍该模型各层级的功能、诊断原理以及模型层次间的信号交互方式。仿真算例分析结果验证了所设计模型的有效性和可行性。Aiming at the problems of low diagnostic performance and the incomplete model of existing fault diagnosis models for the power grid,this paper presents a hierarchical immune model for power grid fault diagnosis.Firstly,it analyzes defense effects of the inherent immune system and the adaptive immune system and their cooperative relationship.Secondly,it discusses the main problems and design requirements of power grid fault diagnosis and proposes the pertinent technical ideas.Finally,referring to the relevant principles of the immune system and the defense mechanism,it adopts the hierarchical diagnosis strategy to construct a hierarchical immune fault diagnosis model.Meanwhile,the paper introduces the functions and diagnostic principles of each level of the model,and the interaction mode between the levels.The analysis results of simulation examples verify the effectiveness and feasibility of the proposed model.
