摘要
随着城市现代化的不断发展,人们对生活的要求越来越高,用电需求在不断增加,也更加重视和关注电力系统的稳定和安全运行,这在增加电力系统负荷的同时也给电力公司的运营带来一定困难,增大了电力系统发生线路故障的概率,特殊的自然环境对电力系统的稳定运行也有较大影响.线路故障开关拒动对于电力系统的安全稳定运行有一定程度的影响,文章分析了220 kV线路开关拒动故障的原因,并对开关拒动引发继电保护动作的行为进行了具体分析.
Picked with the continuous development of city modernization,people’s life demand is higher and higher,electricity demand is in constant increase,people pay more attention to and focus on the stability and security of power system operation,this to increase the load of power system at the same time also bring certain diffi culty to the electric power company,increase the probability of line fault in power system,the special natural environment for the stable operation of power system has great infl uence.In this paper,the causes of the 220 kV line switch failure are analyzed,and the relay protection action caused by the switch failure is analyzed in detail.
