| 摘 要： | 水布垭水电站工程施工供电系统的110kV主供电源的输电线路因长线路＂充电功率＂效应的影响,致使该供电系统的功率因数低,线路的有功功率损耗大。通过对该系统的分析和研究,采取终端变电所低功率因数运行的方式,增大终端的感应无功功率,以冲减输电线路的充电无功功率,从而提高了供电系统的功率因数,减少了输电线路的有功损耗,为该工程的建设减了生产成本。

| Abstract: | Affected by the long circuit Charging Power of 110kV main power of Shuibuya Hydropower Station project, the power factors of the power supply system, the active power loss of circuit is huge. Via the analysis and research against the system and application of lower power factors of terminal substation and amplified terminal reactive power, the charging reactive power is reduced, the induction power factors of power supply is therefore increased, the reactive loss of the circuit is reduced, thus the production cost is lowered. |
