| 摘 要： | 针对V/V牵引供电系统中电气化铁路谐波污染与高负序含量的问题,采用一种铁路功率调节器(RPC).分析了其基本结构和补偿原理,提出了一种预测无差拍和重复式控制相结合的内环电流控制方法.该方法可以解决内环电流指令跟踪快速性的问题,同时也提高了系统的鲁棒性,降低了控制延时与电感偏差对电流控制的影响,并能很好地抑制电流谐波.电压外环采用PI控制,以保证电压外环的稳定.最后通过仿真和实验验证了该方法的正确性.

| Abstract: | In order to solve the electrified railway harmonic pollution problem and a high negative sequence content in V/V traction power supply system,a railway static power conditioner is used.After analyzing its basic structure and compensation principles,a proposed inner loop current control method deadbeat control is focused on and the combination forecasts are repeated.The introduction of this method is such that the inner ring can improve the robustness of the system and reduce the control deviation of the delay and the inductor current distortion,and suppress harmonic current.A simple and convenient PI outer loop control engineering to is selected ensure the stability of RPC DC side.Finally,the simulations proves the correctness of the method. |
