The Architecture and Instance of the Supervisory Information System in Thermal Power Plant
Xin Zhang · Journal of Nanjing Normal University · 2005
Based on the Theoretical investigation of Supervisory Information System (SIS) in China's inland in the past few years and the engineering practice of 4×300MW Unit SIS project in QianBei thermal power plant of GuiZhou, the paper proposes that the architecture of the SIS can be divided into four parts in terms of function. They are realtime/historical database, realtime data collect system, operating date analysis system and configuration display system in client, among which the realtime/historical database is the core of SIS . Then, the paper describes the functions of each parts, and introduces the system structure and function with realization of each parts of the SIS in QianBei thermal power plant.
