摘要
针对铁路电力机车产生的负序、谐波、无功等电能质量问题,传统的两电平变换器型的铁路功率调节器已经无法满足高压大功率应用领域的要求,基于MMC的铁路功率调节器具有明显的优势。以采用V/v接线变压器的牵引变电所为背景,对不同结构的MRPC方案进行分析和对比。最后,总结了3桥臂MRPC方案的优势,通过RT-LAB实时仿真平台,对3桥臂MRPC系统进行了验证,结果验证了该方法的可行性和有效性。
For the problems of negative sequence current, harmonics and reactive power generated by railway locomotives, the traditional RPC based on two-level converter has been unable to meet the demand for high-voltage and high-power areas. RPC based on MMC has obvious advantages over the traditional one. In the background of railway traction substation using V/v connection transformer, compored and analysed different design schemes of MRPC. Finally, concluded the advantages of three-bridge MRPC and used the real-time simulation of RT-LAB to prove the feasibility and effectiveness of this method.
