伴随着智能电网系统的升级换代，电网规模日趋庞大，电网结构愈加复杂，智能电网的故障诊断与继电保护技术越发显得重要。当大规模智能电网系统发生复杂或多重故障时，仅靠单个系统信息和单一诊断手段很难解决故障诊断问题。文中针对大规模智能电网的故障诊断技术，引入了人工智能领域中具有分布式智能特性的多智能体系统模型，通过分模块故障特征信息捕捉机制及区域智能体并行诊断和全局智能体总体诊断的分单元协调诊断机制，在全局信息基础上实现智能电网的故障诊断。仿真测试案例表明，基于多智能体系统的故障诊断技术有效而可靠，并且具有较好的实时监测应用价值。

Along with the increasing development of smart power grid, the fault diagnosis and isolation of smart grid is becoming more and more important in electric power industry. Howerver, it is difficult to tackle fault diagnosis problems through the strength and capability of a single intelligent system based on the traditional methods, it is very essential to further study the fault diagnosis for smart grid. This paper introduces an experimental multi-agent system based fault diagnosis method in smart grid, every agent detects synchronously the corresponding fault information in real-time, through communication and collaboration among agents, all fault information is shared in the multi-agent fault diagnosis system . The simulation results show that the multi-agent based fault diagnosis system for smart distribution grid not only realizes efficient diagnosis and isolation of fault, but also possesses stronger robustness in real-time application.
