摘　　要：地铁供电系统存在谐波污染和功率因素偏低,损耗大等问题。为了解决这些问题,本文设计了一种基于感应滤波技术的新型地铁供电系统方案。新系统可以使得阀侧谐波无法通过整流变压器流入高压网侧,具有良好的谐波抑制和无功补偿效果。仿真结果验证了方案的有效性。There are many problems in the traction power supply system for metro, such as harmonic pollution, low power factor and great power loss. Thus, this paper designs a new traction power supply system based on inductive filtering technology for metro. The new system prevents harmonic currents from injecting into the primary winding through rectifier transformer.Simulation results prove the effectiveness of the proposed design.
