On-line Fault Diagnosis Model of the Hydropower Units Based on MAS

The paper introduced a novel on-line fault diagnosis system model of the hydropower units based on multi-agent system. In allusion to the classical MAS-based fault diagnosis model, it proposes a new function of information interactive between the mission-controlled subsystem and the task decomposition subsystem to increase the transmission rate of control signals and designs the status-monitoring subsystem to detect the abnormal signals directly from local to increase the fault diagnostic sensitivity. In the fault-diagnosis subsystem, a multi-agent interactive parallel structure is designed to meet the requirements of the high reliability and good real-time. A Java-based language so called as JAFMAS is used to build a multi-agent cooperation platform. Experimental results show the effectiveness and feasibility of the proposed method.
