摘要
自然灾害是输电线路的主要故障因素。在统计华中电网直属的500kV输电线路因自然灾害导致的一般及以上的事故案例基础上,按灾害种类、时间、地域、季节等因素对事故案例进行统计分析,总结了输电线路主要自然灾害的成灾机理以及华中电网公司针对每种灾害的预防、应对策略,并对电网抗灾减灾提出相关建议,为输电线路的安全、稳定运行提供参考。
Natural disasters are the main factors of the transmission line fault. Based on the statistical analysis of main natural disasters of 500 kV transmission lines in the central China power grid, this paper investigated the accident cases according to the disaster type, time, areas, season and other factors. Several main disaster mechanisms and prevention strategies for the 500 kV transmission lines were studied. At last, this paper presented some suggestions for the disaster resistance and reduction, which could provide references for the safe and stable operation of the transmission lines.
