摘要
以某城市轨道交通A号线A主变电站为例,在35 kV电缆充电功率测试分析的基础上,开展了电缆等效容抗和长度计算,并仿真分析了当前工况下的谐波电流放大系数曲线,以及35 kV系统短路容量和35 kV供电电缆长度对谐波电流谐振放大的影响。研究结果可为轨道交通的规划、运行及谐波电流的防治提供技术参考。
Based on the charging power test of 35 kV cable,the A main substation of an urban rail transit line A is taken as example to calculate the cable equivalent capacitance and length,and simulate and analyze the harmonic current coefficient curve under current working condition and the influence of the 35 kV system short circuit capacity and the length of 35 kV power supply cable on the harmonic current resonance amplification.The research results can provide technical reference to the planning,operation and prevention of harmonic current of rail transit.
