摘要
平行双边供电系统可以取消分区所处的电分相,提高牵引网供电能力。构建平行双边供电系统的数学模型,能够为电气化铁路牵引供电方案设计提供依据。以牵引网复线直接供电方式为例,建立了平行双边供电系统的数学模型,给出了双边供电均衡电流的计算方法,并推导了牵引网双边供电区间在复线牵引网上下行不并联、末端并联、全并联等情况下的牵引网阻抗;基于Simulink软件搭建了平行双边供电系统的仿真模型,验证了理论推导的正确性和有效性。
The parallel bilateral power supply system can cancel the phase break of the section post and improve the power supply capacity of the traction network.The mathematical model of parallel bilateral power supply system can provide a basis for the design of traction power supply scheme of electrified railway.Taking the double track direct power supply mode of traction network as an example,the mathematical model of parallel bilateral power supply system is established,the calculation method of balanced current of bilateral power supply is given,and the traction network impedance of bilateral power supply section of traction network under the conditions of down track non-parallel,terminal parallel and full parallel of double track traction network is deduced.The simulation model of parallel bilateral power supply system is built based on Simulink software to verify the correctness and effectiveness of the theoretical derivation.
