Research of the on-line hydropower units fault diagnosis based on fuzzy theory and multi-Agent

To improve existing defects of on-line monitoring of hydropower generating units, the paper designs a MAS-based fault diagnosis system model. In allusion to the classic model of MAS-based fault diagnosis system, it improves information interactive features between mission-controlled subsystems and diagnosis task decomposition subsystem to increase the rate of control signal transmission and makes status-monitored subsystem to get abnormal signals directly from factory to increase sensitivity of system. In fault diagnosis subsystem of real-time fault diagnosis system, an MAS-based interactive parallel working structure is designed to meet requirements of high reliability and good real-time. Java-based software so called as JAFMAS is used to build platform to construct a multi-Agent coordination mechanism. Experimental results show the effectiveness of the proposed system.
