摘　　要：为了精准、快速完成水电站变压器的故障诊断,设计基于Multi-Agent的水电站变压器故障诊断系统。变压器状态监控agent将检测到的变压器故障信息发送给系统管理agent,系统管理agent通过通信agent将变压器故障信息发送给变压器故障诊断agent,变压器故障诊断agent利用小波变换方法提取变压器故障特征,并将其作为IFOA-SVM模型输入,完成变压器故障分类后,获取变压器故障诊断结果,该结果通过通信agent显示给用户。实验表明,该系统可有效诊断变压器故障诊断,诊断成功率受系统故障信息丢失率的影响较小,诊断耗时、耗能小,并具有较高故障诊断成功率。In order to complete the fault diagnosis of hydropower station transformer accurately and quickly,a Multi-Agent based fault diagnosis system for hydropower station transformer is designed.The transformer state monitoring agent sends the detected transformer fault information to the system management agent,and the system management agent sends the transformer fault information to the transformer fault diagnosis agent through the communication agent.The transformer fault diagnosis agent extracts the fault symptoms of the transformer using the wavelet transform method and takes them as the input of the IFOA-SVM model.After the transformer fault classification is completed,the transformer fault diagnosis result is obtained.The result is displayed to the user through the communication agent.The experiment shows that the system can effectively diagnose transformer fault diagnosis,and the diagnosis success rate is less affected by the loss rate of fault information.The diagnosis time-consuming and energy consuming are small,and the fault diagnosis success rate is high.
