A Cooperative Monitoring Approach of Hydro Turbine Generator Sets based on Multi-agent Technology

Abstract

Hydro Turbine Generator Set (HTGS) is an organic entity though it is composed by numerous equipments. However, almost all of those monitors applied in plant operate independently. Data and information from those independent systems lack correlation. This situation makes it difficult to determine whether or not there are potential faults. This paper proposes a cooperative monitoring approach based on multi-agent technology. A modified agent reference model is listed and the framework of the whole monitoring system is introduced. Then cooperative work process based on blackboard model and the cooperation mechanism based on operation condition synchronization (OCS) and event synchronization (ES) technology employed in this approach are also introduced. Application shows that this new approach is able to overcome the deficiency of single independent monitoring system for the interpretation of detected fault and health condition assessment.
