| 摘 要： | 本文简述了神朔电气化重载铁路长供电臂末端网压跌落的原因及理论分析，对比分析了接触网电压损失和变电所电压损失的网压提升方法。结合神朔铁路的实际特性，提出了一种在供电臂末端装设动态无功补偿装置的提升网压的方法，并探讨了在供电臂末端进行补偿的优越性，通过对比该装置投运前后的补偿效果，该补偿装置在重载时能有效地将供电臂末端电压提升了8kV，同时系统功率因数保持到0．98以上。

| Abstract: | The paper briefly describes voltage dip of long feeding section terminal on Shenshuo electrical heavy-duty railway, and analyses the reason. Voltage loss of overhead contact line and voltage loss of substation are compared. Combined with real characteristics of Shenshuo railway, a plan of dynamic reactive power compensation device installation on feeding section terminal is proposed. By comparing the compensation effect, the reactive power compensation device can effectively raise voltage on feeding section terminal and meanwhile keep power factor at 0.98 at the same time. |
