The invention relates to a heavy haul railway AT power supply capacity calculation method; when the method is used, an AT power supply heavy haul railway traction cable cut-through power supply scheme is calculated, mathematical models of CTN equivalent impedance, current distribution, voltage loss, CTN tail end network voltage and other electrical parameters are deduced, then the calculation method of the power supply distance is obtained, and the power supply capacity of the scheme is judged. The current heavy haul railway AT power supply scheme is convenient to reform, so that the current heavy haul railway AT power supply system has greatly reduced electric split phases, improved power supply capability and prolonged power supply distance, the operation of a locomotive is safer and more reliable, and the operation speed is improved.
一种重载铁路AT供电供电能力计算方法,本发明使用时,AT供电的重载铁路牵引电缆贯通供电方案进行计算,对CTN等值阻抗、电流分布、电压损失、CTN末端网压等电气参数的数学模型进行推导,进而得出供电距离的计算方法,以判断该方案供电能力,便于对现有的重载铁路AT供电方案进行改造,使得现有的重载铁路AT供电系统电分相大幅减少,供电能力提高,供电距离延长,使机车运行更加安全可靠,运行速度得到提升。
