The21st century is an unprecedented information and network age. Power enterprises should also keep up with the information age, and the information technology promotes the development of power plant automation. Based on modern information technology and real-time process control and management experience of power plant, the concept of Supervisory Information System (SIS) was originally and independently suggested by Chinese experts.According to the operating characteristic of power plant’s production in china and the level of automation control construction, the author firstly studies the background of Supervisory Information System (SIS) for power plant, and states the necessity of SIS settings and the study’s status of SIS at home and abroad in the paper. The author detail investigates the basic concepts including the definition, the basic configuration, the application function of SIS and the distinction and contact with other systems(such as DCS, MIS) in the paper. According to the author’s practical work and beginning with design objectives and requirements, the author designs the detail project of supervisory information system for Taizhou power plant through the following aspects:general layout of network structure, type selection of real-time databases, interface realization and application functions design, and etc.. The detail layout and design in this paper had been adopted and implemented by Taizhou power plant.The SIS project of Taizhou power plant mainly rests on the fifth phase of extension project and is implemented at the same time. There has been a completed PI real-time network and database system for the first to forth phase of generators in the existing plant. That making full use of the existing equipment and appropriate technology upgrade, which was also the highlights and innovations, was the key of successful implementation of the Taizhou power plant SIS project with the unity of economics and high performance. This research was of great significance for the expansion and renovation of other existing power plant.
