Abstract

The key to controlling harmonics in high-speed railways is to get information on its harmonic feature. In this study, a continuous 24 h harmonic observation is carried out in Ji'an West traction substation of a typical Chinese high-speed railway. In both the 24 h operating period and the two train driving processes, the features of harmonics of 27.5 kV buses are studied under multiple operating modes, which finds that the voltage and the current harmonic content mainly consist of low-order harmonics below the 11th order with high-order harmonics that ranges from 13th to 31st and 89th to 99th order. The law that the harmonic distribution changes with the load current is derived. Calculation results show a power function relationship between total harmonic distortion and bus current. In regenerative braking modes, the harmonic content is higher than traction with less high-order harmonics. Finally, the authors find an admittance matrix coupling between the 3rd to the 31st order harmonic voltage and current for simplified modelling of the harmonic transmission.

中国高速铁路27.5kV牵引电力系统谐波特征

高速铁路谐波控制的关键是获取其谐波特征信息。本研究对我国典型高速铁路集安西牵引变电站进行了24 h连续谐波观测。研究了27.5 kV母线在24 h运行周期和两次列车行驶过程中多种运行模式下的谐波特征，发现电压和电流谐波含量主要由11阶以下的低次谐波组成，高次谐波在13阶至31阶和89阶至99阶之间。导出了谐波分布随负载电流的变化规律。计算结果表明，总谐波失真与母线电流呈幂函数关系。在再生制动模式下，谐波含量高于牵引，高次谐波较少。最后，作者找到了3 ~ 31次谐波电压和电流之间的导纳矩阵耦合，简化了谐波传输的建模。
