摘要
根据国内电气化铁路供用电现状,对电网分层分区运行方式下以110kV电压等级向电气化铁路供电对电网的影响及其特点进行了介绍和分析,提出在负序、谐波等问题难以解决的情况下,采用专用变压器或220kV电压等级向电气化铁路供电的方案,抑制电气化铁路对电网的影响。
In this paper,the influence of electrified railway on the grid of Xuzhou under 110 kV joint schemes and grid operation mode by level and district are discussed;two joint schemes of electrified railway, which are special transformer or 220 kV voltage level, are put forward to reduce the influence of electrified railway.
