有轨电车非接触牵引供电系统供电计算研究

Research on Power Supply Calculation of Non-contact Traction Power Supply System for a Tramway

非接触供电在城市轨道交通牵引供电系统中的应用是目前研究的热门,但对于非接触城市轨道交通牵引供电系统供电计算的研究较少。本文提出一种基于DC 1 500 V外部供电网络的非接触牵引供电系统拓扑结构,分析外部直流供电系统的整流机组、电能变换装置和初级发射线圈与次级拾取线圈的供电模型,并给出供电计算算法和步骤,最后通过具体算例验证该算法的正确性。

The application of non-contact power supply in traction power supply system for urban mass transit is a hot research topic;however,there are little researches on calculation of power supply by non-contact traction power supply system of urban mass transit.The paper puts forward a non-contact traction power supply system topological structure based on external power supply system of DC 1 500 V,analyzes the power supply models for rectifier sets,energy converting devices and primary transmitting coil and secondary pickup coil of the external DC power supply system,provides the power supply calculation methods and procedures.The calculation method is finally verified to be correct by actual calculation examples.
