摘要
设计了一种基于三相电压型PWM整流技术的新型城市轨道交通直流牵引供电电源。整流装置采用同步旋转坐标系电流控制和电压空间矢量调制(SVPWM)技术,实现有功电流、无功电流的独立控制,提高电压利用率。试验证明,该控制方法响应速度快,稳态性能好,供电电源以单位功率因数运行,电流谐波含量小,达到了预期设计要求。
A design of the DC traction power supply of the urban rail transit is proposed based on three-phase voltage source PWM rectifier.The current control based on the synchronous rotating frame and the space vector PWM are used for the rectifier to achieve the current decoupling and high voltage utilization ratio.The experimental results show that the control system reaches the design requirements and has fast dynamic response, excellent steady-state performance, unity power factor and low harmonic content.
