摘要
现阶段,随着中国电力事业的不断发展,对可靠性较高的基础设施也变得更加依赖。为了确保220 kV及以上电压输电线路的安全运行,电力企业应该不断完善电力系统应用过程中的服务功能,重视对电压线路的继电保护,促使220 kV电力系统可以处于良好的运行状态。基于此,首先分析了220 kV及以上电压输电线路继电保护的可靠性,然后进行了可靠性影响因素分析,最后介绍了继电保护装置状态的检修,并进行了实例验证,希望能够为电力系统的正常运行提供帮助。
At present with the development of China’s power industry and the improvement of production level the dependence on infrastructure with higher reliability performance has been improved to a certain extent. In order to ensure the safe and stable operation of 220 kV and above voltage transmission lines power enterprises should constantly improve the service functions in the application process of power system pay attention to the relay protection of voltage lines and promote the 220 kV power system to be in a good operation state. Based on his paper it first elaborated the principle and type of transmission line relay protection line relay protection and finally through the example of computer reliability impact factor analysis and relay protection equipment maintenance.
