对电力系统继电保护若干问题的研究

Research on Several Problems of Relay Protection in Power System

电力系统的安全稳定运行离不开继电保护技术,而继电保护在构建过程中需要从实际存在的问题出发,根据电力系统继电保护经常出现的问题,探讨相应的解决措施。电力系统继电保护中常见的问题主要包括拒动、越级或延时跳闸、电子互感器问题、时钟同步问题以及其他问题等。因此,阐述对继电保护装置的要求,详细分析其常见问题,并提出相应的解决对策。

The foundation of safe and stable operation of power system needs to be ensured by power protection technology,and the relay protection needs to start from the actual problems in the construction process,according to the problems often occurred in the relay protection of power system,the corresponding solving measures are discussed.The common problems in power system relay protection include switching over or delay trip,electronic transformer,clock synchronization and other problems,so it is necessary to focus on these aspects.In this paper,the characteristics and functions of relay protection are described,and then the common problems are analyzed in detail.Finally,the corresponding countermeasures are put forward.
