摘要:
早期的城市轨道交通牵引供电系统主要采用二极管整流机组供电，列车制动时产生的制动能量被制动电阻消耗，造成较大能源浪费。基于IGBT（绝缘栅双极型晶体管）的PWM（脉冲宽度调制）整流器具有四象限工作能力，能量可双向流动，不但能回馈列车制动能量，还能稳定直流网压、优化供电环境，具有很高的推广价值。重点研究了整流机组与双向变流器混合供电的控制策略，并分析了混合供电模式对城市轨道交通牵引供电系统系统的影响。
Abstracts:
At the early stage, diode rectifier unit was adopted as the main power supply system for urban rail transit, but the braking energy produced by vehicle braking was consumed by braking resistance, causing huge energy waste. The PWM (pulsewidth modulation) rectifier based on IGBT (insulated gate bipolar transistor) has four-quadrant working ability with bidirectional energy flow. It could not only respond to the vehicle braking energy, but also stabilize the DC network voltage and optimize the power supply environment, therefore has high promotion value. By focusing on the control strategy of hybrid power supply between rectifier unit and bidirectional converter, the influence of hybrid power supply mode on urban rail transit traction power supply system is analyzed.
