Research and implementation of power plant information integrating system

To promote information integration of heterogeneous application systems in power plant, this paper proposes to construct information integrating system on the basis of introducing the power plant integrated automation system. Technologies of XML are analyzed, model of XML based power plant information integrating system is designed, and main components of the system and their implementations are introduced in detail. Main functions of the model have been developed experimentally in lab and the feasibility and validity of the model have been approved by running results of system, which will provide a scheme for implementing information integrating system of power plant and interconnecting of three-class network system, including DCS, SIS and MIS, and Internet, and make an attempt at the same time.
