The Application Research Of Generator Transformer Unit Protection In Weifang Power Generation Company Limited

With the rapid development of the national economy, the safe and stableoperation of power system b more and more important, and the large thermalgenerator transformer group is an important and valuable primary equipment in thepower system, uninterrupted power supply for the reliable operation of the unitnormal operation, the power of system users, ensuring the quality of electric energyand so on, all played an important role, so for the large generator transformer unitprotection requirements are also getting higher and higher.From the basic principle of microcomputer protection and the requirements ofpower system, and discusses the development trends of the history, present situation,characteristics and technology of relay protection of microcomputer relay protection;in depth analysis of the main fault, large generator and transformer abnormaloperation and protection should be configured, analyzes and studies the current useof Weifang Power Generation Co. Ltd. the main protection principle, RCS-985typegenerator transformer microcomputer protection setting value configuration, specificproblems tripping outlet, DC power supply configuration, the two circuit wiring,man-machine interface and so on Application of. Combining with the field ofgenerator transformer unit protection in practical case study of existing limitationsand equipment protection configuration aspects of the problems, puts forwardimprovement schemes and suggestions, for the optimization and improvement ofgenerator transformer unit protection has practical significance. The purpose of thisstudy is to explore the more perfect protection configuration, the elimination of thecurrent problems and hidden dangers, the application of large generator transformerunit protection better in practical, safe, reliable, units and stable operation of thepower system to escort. Research indicates that the Weifang company of generatortransformer unit protection application is successful, can provide a valuablereference for other applications of generator transformer unit protection...
