Control-decision and integrated information system of power plant

This paper introduces the structure of the integrated information system of the power plant. This system can be classified by two components, one is the integration of the control and diagnostic system, the other is integration of the management information and real-time information. Multi-goal optimization and coordination can be used to realize the integration of the control systems, and failure trend-based forecasting methods can be used to realize the integration between the control and diagnostic systems. Through the inter-link between the distributed control system (DCS) networks, the information can be shared by real-time system and management system.
