Abstract
The whole power plant and the process of power generation are so complicated that comprise so many apparatus and systems. Any small part would make the power plant in fault. In order to find and study the fault reasons easily, the whole power plant could been divided into several subsystems in several levels. Study on the fault records of 600MW units, manufactured by Shanghai Electric Power Generation Equipment Co., Ltd. (SECPG), which are running in China. All the records are from China Electric Power Reliability Management Center. With the help of fault matrix, a fault tree covering all fault records on all units has been established. And the fault tree has 5 levels: the whole power plant, turbine and generator, all faulty components, the certain power plants and fault causes. Turbine has been divided into 9 parts, generator has been divided into 4 parts and there are 10 kinds of fault reasons. So it is clear that the connections among all the parts, faults, causes and elements in the final fault tree. The final fault tree and the matrix of faults are digitized, integrated and visualized to represent the faults. The digitized representation is the most imaginable and integrated.
