摘要
本文针对城市轨道交通设计了混合式能量反馈牵引供电装置,基于12脉波整流器与PWM整流器共同构成,PWM整流器双向变流时,还可为12脉波整流器补偿谐波。经过仿真试验验证,结果表明基于合理把控PWM整流器直流外特征,可自动分配整流器功率,并保障直流网压稳定性,符合设计标准;以多旋转坐标系电流控制体系为载体,混合式能量反馈牵引供电装置可通过PWM整流器针对12脉波整流器补偿谐波,谐波含量显著降低。
In this paper,a hybrid energy feedback traction power supply device is designed for urban rail transit.Based on the combination of 12 pulse rectifier and PWM rectifier,PWM rectifier can also compensate harmonic for 12 pulse rectifier when bidirectional converter.The simulation results show that based on the reasonable external DC characteristics of PWM rectifier,the rectifier power can be automatically distributed,and the stability of DC network voltage can be ensured,which meets the design standard;the hybrid energy feedback traction power supply device can compensate the harmonic for 12pulse rectifier through PWM rectifier,and the harmonic content is significantly reduced low.
