提高功率因数,降低电力设备的损耗

Improving the Power Factors and Reducing the Losses of Electric Power Equipment

功率因数反映了负载从电源接受的视在功率中,有多少转化成了有功功率。功率因数越高,即无功功率越少,发、供、用电设备越能够充分发挥其能力。提高功率因数的措施主要是补偿无功功率,以取得最大的节能和经济效益。

The power factor reflects that how much load has been transformed to be active power from the apparent power received from source.The higher the power factor is,namely the less the reactive power,and the more capabilities of electrical power equipment will distribute.The measures to improve the power factor are mainly to compensate reactive power to achieve maximum energy efficiency and economic benefits.
