摘要
针对城市轨道牵引供电系统设置的制动能量回馈装置,本文提出了一种兼备配电网谐波电流治理能力的制动能量逆变回馈与谐波电流抑制方法;该方法能够灵活地实现有源滤波与制动能量回馈模式的切换,净化了牵引供电系统,提高了制动能量回馈装置的利用率。为了有效抑制牵引供电系统产生的谐波电流,本文对24脉波移相整流变压器组中不同序谐波电流的传递规律和基于矢量谐振控制器的电网侧谐波电流闭环控制方法进行了研究。Matlab/Simulink平台的仿真结果验证了所提控制方案的有效性和正确性。
Aiming at the braking energy feedback device set up in urban rail traction power supply system,a braking energy feedback and harmonic current suppression method with harmonic current control ability of distribution network is proposed.This method can realize the state between active filter and braking energy feedback mode flexibly,purify the traction power supply system and improve the utilization rate of braking energy feedback device.In order to restrain harmonic current in traction power supply system effectively,this paper studied the transfer law of harmonic current of different sequence in 24-pulse phase shift rectifier transformer,and the closed-loop control method of harmonic current on grid side based on vector resonance controller.The simulation results of Matlab/Simulink platform verify the effectiveness and correctness of the proposed control scheme and method.
