| 摘 要： | 地铁机车采用直流牵引，具有波动性强、系统谐波含量丰富等特点．极大地威胁到电力系统的安全稳定运行。为了分析西安地铁对公共电网的影响，应用MATLAB／Simulink软件对即将投运的西安地铁2号线24脉波整流设备和牵引供电系统建模，并对其接入西安市公共电网后产生的谐波进行计算。结果表明：地铁负荷的变化对公网谐波含量的百分比影响较小；地铁供电系统23、25、11、13次谐波所在的比例最大，对公共电网电能质量的影响也最为严重。建议对以上4种谐波采取相应的治理和防护措施；随着地铁牵引负荷的增大。建议预留谐波抑制设备的安装位置。

| Abstract: | Metro DC traction locomotives have characteristics such as strong volatility and rich in harmonic content of the system, which is a grave threat to the security and stability of power system operation.In order to analyze the impact of Xi'an subway on public power system,this paper establishes models of 24-pulse rectifier unit and traction power supply system of Xi'an No.2 subway based on the software MATLAB/Simulink.And it calculates the harmonics formed by locomotives after those models have been connected... |
