摘要
作为电力系统的一个特殊用户,高速电气化铁路具有非线性、不对称性、波动性和功率大的特点。文章简要介绍了武广电气化铁路情况,并以泉口牵引站接入咸宁电网的电能质量测试结果为例,分析高速电气化铁路的负荷特性以及其产生的负序和谐波对电力系统产生的影响,最后提出了一些治理措施以减轻电气化铁路对湖北电网的影响。
As a special user in power system, high-speed electrified railway possesses the features of nonlinearity, asymmetry, fluctuation and large power. This paper briefly describes the Wuhan-Guan- gzhou high-speed electrified railway, and takes Quankou traction station power quality lest results for example, the load characteristics of electrified railway, the impacts of negative sequence and harmon ics generated from electrified railway to power grid are analyzed. Then some controlling measures are proposed to ease the impact on Hubei power grid.
