Planning And Designing Of Thermal Power Plant Supervisory Information System

Based on the background review and present state analysis of power plant supervisory information system(SIS), We give a deep discuss about its structure,function, network and database. From the view of application, SIS is a interlayer of plant information system, developed for process management and device maintenance stuff.In the SIS network chapter, network demand analysis was present first, then we gave the rule for network designing and device selecting. Real time database (RTDB) play a important rule in SIS system, in this part, we discussed one of its core technology—data archiving mothod, then , as a example,one of the most popular RTDB —iHistoran wes described. At the end of the paper, a SIS scheme concerned with Baotou Thermal Plant Project was introduced, and fortunately, the scheme was accepted by the compony.
