A Fault Diagnosis System Based On Recorded Fault Data At The Dispatching Centre In Power System

This paper analyzes detailedly the methods of power system fault system with the help of recorded data, which is collected at dispatching spot, under the circumstance of complex fault. A method of diagnosis system based on "soft protection model" is put forward. A number of methods of fault location were studied in this paper. Then a double terminal location method based on improved arithmetic is presented, which is simple, applied, and of good precision. A power system fault diagnosis system based on recorded fault data is developed in this paper. A good many functions can be realized, such as fault recorded message management, fault diagnosis, and protection behavior appraisement etc. The whole system was tested by ATP(The Alternative Transients Program) or MATLAB.Wang Ying (Power System and Its Automation)Directed by Prof. Wang Zengping...
