Research On The Theory And Demonstration Of Carrying Out Conditional Maintenance For The Power Enterprises In Chinese Power Market

Under the condition of power market and the separation of power network and power plant, conditional maintenance may improve the us- able rate of the generating sets, prolong the period of maintenance , at the same time reduce the cost. It measures up the principle of 揺nter the power network against competition in price and cut down the cost in Chinese electrical industry, and has gained far and wide attention by power enterprises. Applying reliability and statistic method ,on the basis of detailed in- vestigation in Junliangcheng Power Plant of Tianjin Electrical Power Corp. , in this paper statistical data is analyzed, fault mechanism is studied, the status of equipment is valued , and the mathematical model of the subsystem of steam turbo generator, boiler and electric for conditional maintenance is established, an self ?contained expert system is developed to simulate and forecast the change pattern and tendency of their condition. The software may record data and build proposals for equip- ment management, maintemance management and spare part manage- ment automatically after being run. At the end of this paper, the opti- mized object and apparatus of carrying out condition monitor is selected hereby, the cost / profit of the project is analyzed, and proposals for the reform of equipment maintenance plan and mode are propovided, so that the power enterprise may gain best yield under the condition of power marked , and be on a good wicket in the competition.
