| 摘 要： | 功率因数是供电系统中的一个重要指标，负荷的功率因数太低对系统运行很不利，提高功率因数可提高电力系统供电能力，降低网路的功率损耗，减少网路中的电压损失，提高供电质量，降低电能成本，可通过正确选择电气设备、保证电气设备合理运行、人工补偿无功功率等方法提高功率因数。

| Abstract: | The power factor is an important index in current supply system. The lowest power factor of the load is very unfavorable for the operation of the system. The increase of the power factor can increase the current supply ability of power system, reduce the power loss in network, improve the quality of current supply and lower the cost of electric energy, through right selection of electrical equipment, guaranteeing the rational operation of electrical equipment, artificial compensation for reactive power, etc. the power factor can be increased. |
