摘要
提出一种基于三相电压型PWM整流器的新型轻轨牵引供电系统,具有节能效果好、功率因数高、谐波含量小及电压稳定性好等优点,并且易于模块化和冗余设计。重点介绍了变流系统的主电路拓扑、PWM整流器的控制策路、并联控制策略和错时矢量调制(ISVM)技术。仿真和实验结果表明该系统可行。
In the paper, a novel traction power supply system of railways is proposed, which bases on three-phase voltage source PWM rectifier. The merits include energy saving, high power factor, low harmonic current, easy modularization and easy redundancy design. The circuit topology, PWM rectifier control scheme, a novel parallel control scheme and the ISVM technique are mainly introduced in the paper. Simulation and experimental results show the feasibility of the presented system.
