摘要:
针对电力机车过分相时导致变电所跳闸、电弧烧损接触线等问题,建立过分相过程的高阶等值电路,理论分析影响过电压的因素,得出机车过电分相的时刻是引起过电压的决定性因素,高压互感器的饱和引起铁磁谐振过电压是造成设备绝缘击穿和保护装置误动作的主要原因。提出了利用自动过分相装置的强迫信号、机车速度与接触线的电压相位信号来控制电力机车达到过电分相的时刻来抑制过电压产生的新方法,实现无过电压通过分相。利用电磁暂态仿真软件PSCAD/EMTDC 对过分相过程及抑制方法进行仿真验证。仿真结果表明,新的控制方法可以有
Abstract:
Overvoltage problem caused by electric locomotive passing the neutral section, always result in traction substation trip or the arc eroding the contact line. In order to solve this problem, a high order circuit was established to analyze the overvoltage problem and found that the time of locomotive passing the neutral section was the conclusive factor causing overvoltage, and ferro-resonance overvoltage caused by high-voltage transformer saturation was the main reason leading to equipment insulation breakdown or protection’s mis-operation. A new method was pointed out by utilizing auto-passing neutral section device force-breaking signals, speed of locomotive and contact line’s voltage phase angle to realize the locomotive passing the neutral section without overvoltage. Electromagnetic transient simulation software PSCAD/EMTDC was used to simulate the process of passing the neutral section and the overvoltage restrain method. Simulation results indicated that the new overvoltage restrain method could efficiently control the overvoltage less than 50 kV and improve the security stability of the locomotive operation.
