Research Of The Excitation Regulation System Based On The EX2100

With the scale of the modern power system and the capbility of the single gener-ator being continuously ampliative, the power system and the generator develops higher request for the reliability and stability of modern excitation system. In China, there are some problems in it yet. The problems are: the connection among parts in excitation regulation system is so tight that it is easy to go wrong ; it is difficult for maintenance and upgrade. The paper develops the"three confirming two"multi-channels redundancy policy, resolves the problems of switching logic ecomplexity and controlling difficultly and settles based the EX2100 excitation system of sulig gas power plant;The imagine of the net excitation regulation system is taken the lead in the paper, by decentralizing the sample and control into the parts of the system, a kind of a new all distributed excitation regulation system is constructed; The example proves that the excitation regualtion system provided in this paper is stable, high reliable and has excellent performance.
