The Supervisor Information System Of Thermal Power Plant Research And Application

The supervisor information system (SIS) of thermal power plant factory is a important constitute part in power information system, and make distributed control system ( DCS) and Enterprise Management information system (EIS) combinate availably. If the electric power business enterprise want to increase to produce with manage the efficiency, increase to labor the rate of production, they must pay attention to SIS developments.First, this paper states the source of the sis, it's a new concept given by Chinese's information worker after studying the processing between the distributed control system( DCS) and the Enterprise Management information system (EIS). It is covered consciously extending in power plant safety and economic management, also it's a indispensable tool in modern thermal power plant producing management. This paper compares the technique of sis and real-time database between the domestics and the international SIS, the technique of sis is gradually maturing.Second, the paper states the strategy of SIS in power plant developments and a few risks that need to be noticed .The SIS developments should to adopt the whole programming and divide the method for into practice of step. It is not only make the investment validly distribute and reasonably but also make the production management saluted initiative that need to be solved quickly, and also increase production efficiency and avoid the risk of the item the whole. Analyzed the reason in SIS developments processing that easily result, data mistake rate and the whole safety is two greatest risk in the SIS developments.Finally, writer states detailed from the SIS total design, the arrangement of the system soft and hardware which combination the SIS development in its business. The SIS should apply large mature real/ history data and science date gathering way between SIS and DCS ,should have the initializing developments to processing management with unit performances calculation and analysis of consumption that is important in safety and economic, It can make the investment back quickly, and validly lower the generate electric tying of business enterprise the cost.
