摘要
电力系统中,负载多为感性用电设备,负载在吸收有功功率的同时,还需要大量的无功功率进行能量转换。若功率因数过低,会使电源利用率降低。提高功率因数,提高企业用电质量,最大限度的节约能源。
In electric power system, electric load, which basically belongs to induced power consumption equipment, absorbs the active power and meanwhile, it also needs a great deal of wattles power to exchange energy. If the power factor is too small, it will lead to decline of power utilization, Therefore, power factor improvement can improve enterprise＇s quality of power consumption.
