| 摘要：城市轨道交通变电所多采用24脉波整流器满足列车直流供电需求，输出电压纹波系数低、功率因数高、网侧电压波形畸变小。采用延边三角形方案进行移相设计，实现多重化、多脉波的移相叠加整流技术，具有设计简单、增设变压器容量小、经济性良好等优点。基于移相变压器的矢量模型推导延边三角形移相的工作原理、绕组仿真参数以及电气联结方式。搭建Matlab/Simulink的24脉波移相整流仿真模型，并设计仿真算例进行验证试验，仿真试验结果表明该建模方案的可行性及有效性。 |

| Abstract:City Rail Transit substation mostly use 24-pulse rectifier to meet the demand of train’s DC power supply, which has the advantage of lower ripple coefficient voltage, higher power factor and smaller waveform distortion of the grid side voltage. The multiple, multi pulse rectifier technology that based on prolonged delta connected transformer, is simply designed and has smaller addition of transformer capacity and good economic performance. The working principle, the simulation parameters and the electrical connection of the prolonged delta connected transformer are derived based on the vector model of the phase shift transformer. The 24-pulse Rectifier’s simulation model has built based on Matlab/Simulink, and the simulation cases have been built. The simulation results demonstrate that the modeling scheme is feasible and effective. |
