Abstract


With the development of national economy recently, the county power network develops quickly. Also, the county dispatch automatic system gets the fast improvement and has the very high level, which plays an important role in safe and economic operation of power networks. The extensive application of dispatch automatic system has improved the efficiency of power gird and has changed the work condition of county operators to handle the power grid accidents, which is favor for people to handle the power grid emergency more accurately and faster, and plays a significant part in development and stable operation of county power grid. In order to get the dispatch automatic system reliable operation,we should do a good job of handle dispatch automatic system failure processing to make it plays a important role in economic dispatch and safe operation.DF8002 system is developed by Yantai Dongfang Electronics Information Industry Co., Ltd. It has been put into use in Huizhou Boluo power electricity bureau to ensure the security and stability of the Boluo power grid. However, during the operation there have been fault of system failures, communication channel bit error, wrong remote signalling, failure to operate the remote control and, finally, the database is imperfect, which is bring the risk for power system operation.According to the characteristics of the county dispatch automatic system, its function and organizational structure should be achieved as proposed in this thesis. A varity of failures(system failures, communication channel bit error, wrong remote, failure to operate the remote control and the imperfect database)during operation of the dispatch automatic system for DF8002 is analyzed in depth, and the corresponding approach is proposed, which provide reference for handling failures of other dispatch automatic system.This thesis have analyzed a variety of common faults of DF8002 dispatch automatic system, which improves the function application level of dispatch automatic system, and ensures that the dispatch automatic system provide the correct, real-time, reliable data and information for power grid.
