| 摘 要： | 本文根据测试数据对绥中北牵引变电所谐波电压问题进行分析。认为谐波源来自系统侧,除了非线性负荷外,主要是由大型电力变压器激磁电流所造成。在电网负荷低谷时段,由于电压的升高使激磁电流畸变程度进一步加剧,造成绥中北变电所220 kV母线出现较高的谐波电压。

| Abstract: | Based on the test data of Suizhongbei electric traction substation, this paper analyzes the harmonic voltage problem. The harmonic comes from power system side, which is caused mainly by exciting current of the large capacity transformer besides the nonlinear loads. During the low load time in power system, the exciting current distortion becomes more intense because of the voltage rise and causes higher harmonic voltage in 220 kV bus bar of Suizhongbei traction substation. |
