摘要:
由电能质量和电分相引起的机车速度、牵引力损失是电气化铁路传统牵引供电系统面临的主要问题之一。对此,文章提出了一种同相供电系统,其采用不等边牵引变压器,整流侧采用双闭环控制、逆变侧采用输出电流闭环控制,不仅可以根据负载情况实现功率的动态调整,而且还能进行电压相位变换,取消变电所出口电分相。理论分析和仿真结果验证了该系统在平衡负荷、抑制负序方面的有效性。
Abstract:
Loss of operation speed and traction force, caused by power quality and neutral section, is the main problem of the electric railway’s traction power supply system. It proposed a co-phase traction supply system based on Vv or Scott connected traction transformers, which adopts double close-loop control in the rectifier side and output current close-loop control in the inverter side. The system can not only adjust power dynamically according to practical load, but also realize communication of voltage so as to cancle the neutral section near the substation. Results of theoretical analysis and simulation show the validity of the system to balance load and suppress negative sequence current.
