功率因数是指电力网中线路的视在功率供给有功功率消耗所占百分比,是电力系统的一个重要的技术数据。功率因数的高低涉及发电设备和用电设备等能否充分利用电能,提高功率因数可以充分的发挥发、供电设备的生产能力、减少线路损失、改善电压质量,是缓和电能供需矛盾,减少企业经济支出的有效措施。在能用缺乏的今天,节约能源、提高能源利用率是非常重要且实际的问题,因此,提高供电系统的功率因数有其重要意义。
Power factor refers to the percentage of active power consumed by the apparent power of the line in the power network and is an important technical data of the power system. Power factor involves the level of power generation equipment and electrical equipment, such as the ability to make full use of power, improve the power factor can fully play hair, power equipment production capacity, reduce line losses and improve voltage quality is to ease the contradiction between supply and demand of electricity and reduce business economics Expenditure of effective measures. In the absence of energy, energy conservation and energy efficiency improvement are very important and practical issues. Therefore, it is of great importance to improve the power factor of power supply system.
