Abstract
This paper discusses the basic concepts, composition, fault diagnosis methods and challenges of power plant relay protection system. This paper introduces the architecture, main equipment and components and system operation process, so that the readers have a comprehensive understanding of the whole system. Focusing on the fault diagnosis method of relay protection in power plants, several main diagnostic methods such as empirical judgment method, data detection method and signal state analysis method are introduced, and their application effect and advantages and disadvantages in different situations are analyzed. These methods provide an important technical support for the subsequent fault diagnosis work. The challenges of power plant relay protection are analyzed. The diversity of failure types and the complexity of failure causes increase the difficulty of diagnosis; the high requirement of real-time and accuracy poses higher challenges to diagnostic technology and means; the rapid upgrading of technology and equipment brings new problems of compatibility and operation and maintenance management; finally, the complexity of operation and maintenance management and the shortage of personnel training are also urgent problems to be solved. Provide corresponding strategies to reduce the probability of failure through preventive maintenance strategy, including regular detection and evaluation and strengthening routine inspection; actively introduce intelligent diagnosis technology, such as intelligent diagnosis system and real-time monitoring and early warning mechanism to improve the accuracy and efficiency of fault diagnosis; establish emergency response mechanism and rapid recovery measures to ensure rapid response and restore system operation; continuously optimize and improve the performance of power plant relay protection system through technical and equipment upgrade and feedback and improvement mechanism.
