| 摘 要： | 功率因数是衡量电源利用效率的重要因素,也是影响牵引供电系统效率及输电线路末端网压的重要因素。通过现场测试研究朔黄铁路牵引负荷对变电所功率因数的影响规律,发现牵引负荷对进线电源侧和馈线侧功率影响方式存在较大的差异:电源侧功率因素随牵引负荷的增大而减少,馈线侧功率因素随牵引负荷的增大而增大。通过研究认为变电站无功补偿方式是造成该现象的主要原因。最后,对朔黄铁路如何改善电能质量及扩能提出了建议。

| Abstract: | Power factor is an important factor to measure power source utilization efficiency,also is an important factor affecting both the traction power supply system efficiency and the end-voltage of power supply network.A field test about the influence of traction load on the power factor of substation was conducted for Shuo-Huang Railway.And then a great difference was found out: when the traction load of heavy haul railway was increased,the power factor of the power supply incoming line side was decreased,but the power factor of feeder side was increased.The paper thinks that: it is the reactive power compensation mode of substation that plays the leading role in causing this phenomenon.Finally,suggestions are presented in this paper about how to improve the power energy quality and how to expand the power capacity for Shuo-Huang Railway. |
