The Project Of Online Inspect And Condition Based Maintenance In The 200MW Fossil Power

With the further deepen of our country's electric power reform and the model of detachment between wire network and factory has been established, the economy of power plant will be calculate separately. How to decrease the cost of generate electricity and improve the benefit continually are faced with a great problem.The running expenses of power plant is conposed of three parts: expend of raw and processed materials(contain fuels etc.), payout of labour force, and run and maintenance costs. The expend of fuels is mainly rest with the factors of market, so, cutting the costs of run and maintenance becomes many power plant's chief target to decrease the cost of production. I.e. the improve of the equipment's reliability and the require of the cost of repair benefit retio. Consequently, the mode of inspect the state of equipment and examine and repair before the equipment has occurred a material malfunction become advance techonology in the area of electric power.This paper analyse the feasibility and necessity of examine and repair about the QianGui Co. LTD of generate electricity base on the frmework of GuiZhou wire network and the run state and exerience of the factory. At the same time, in the base of the lucubrate and analyse of stats examine in domestic and abroad, this paper has analyse the abrupt librate of steamer generator by online data check in PanCountry Power Plant. It acquire obvious effect and prove the applicability and feasibility about the examine in power plant by take correspond measures to ensure the normal operate of the set.In this method of state examine, and the utilize of the analyse and comparative method combined with the practice of PanCountry Power Plant, I establish a scheme of state exame and repair for the inc. And it has completed the construct of collectivity project and the basic principle of design, system scheme collectivity, item content, data collection of host and assist computer, analysis and data manage system, portable libration data analyse and collection, DCS net contact with MIS net, and data longdistance transfers. Finally, it presents rational advices aim at the further apply of the project of deepen state examine and repair.The method adopted in this thesis can also used in other power plants as reference.
