Fault diagnosis based on MFM and MAS for generation unit

MA Jingming1,2,ZHAO Yun1,WANG Bin1,WU Weixiong1,GU Xiaojun1,3(1.College of Mechanical & Electrical Engineering,Jiaxing University,Jiaxing 314001,China; 2.College of Mechanical & Electrical Engineering,Jiangxi University of Science and Technology,Ganzhou 341000,China;3.College of Mechanical & Energy Engineering, Zhejiang University,Hangzhou 310027,China)  
A distributed MAS(Multi-Agent System) composed of the monitoring and diagnosis Agent,diagnostic method Agent,management Agent,blackboard Agent and so on is proposed for the fault diagnosis of steam turbine generator unit.The functional analysis method is used to realize the cooperation of the MFM(Multi-level Flow Models) and the distributed MAS for fault diagnosis.When abnormity occurs,the monitoring and diagnosis Agents cooperate with each other,and based on its MFM,the fault searching path is set up according to the connections among energy,substance and information streams to realize the fast fault locating.According to the features of the faulty node or equipment,the specific MAS is organized by the diagnostic method Agent and the monitoring and diagnosis Agent under the harmonization of the management Agent to realize the precise fault diagnosis.
