| 摘 要： | 为解决异相牵引供电方式存在的电能质量和电力机车过分相问题,将有源补偿和无源对称补偿技术相结合,提出基于平衡变压器接线方式的混合式同相牵引供电系统结构。文中给出混合式同相供电的统一补偿理论、无源补偿系统的无源元件参数计算方法、有源补偿的控制策略、无源和有源补偿的协调控制策略。最后,以采用YNvd接线方式的平衡变压器为例,采用MATLAB软件仿真验证该系统方案和控制策略的正确性。

| Abstract: | In order to control power quality and cancel neutral sections in out-phase power supply of existing electrical railways,the new co-phased traction power supply system construction was presented on the basis of the balanced transformer,and active compensation and passive compensation technology.The theory of unified compensation,the calculating method of passive compensation parameters,the active compensation control strategy and the coordinated control strategy of active compensation and passive compensation were given for the co-phased power supply.Simulation by MATLAB was made with the YNvd connection-mode transformer.The results verify the correctness of the presented system scheme and control strategy. |
