摘要
针对宁夏电网220 kV及以上部分线路保护信号传输通道配置存在的问题,按照"国家电网公司十八项电网重大反事故措施"具体要求对其进行了详细分析,并提出了相应的优化策略。应用结果表明:该优化策略体现了线路保护信号传输通道的有效性和合理性,使其安全可靠性得到显著提升。
Aiming at the problems of configuration for 220 kV and above power line protection signal transmission channel in Ningxia power grid,according to specific requirements of ‘18 major anti-accident measures of the state grid’,puts forward corresponding optimization strategy. The application result shows that the optimization strategies can incarnate the availability and rationality of the line protection signal transmission channel,markedly improve safety and reliability of the channel.
