摘要:依据用电设备的功率因数，可测算输电线路的电能损失。通过现场技术改造，可使低于标准要求的功率因数达标，实现节电目的。本文分析了无功补偿的作用和补偿容量的选择方法，着重论述了低压电网和异步电动机无功补偿容量的配置。结合应用实例说明采用无功补偿技术，提高低压电网和用电设备的功率因数，已成为节电工作的一项重要措施。关键词: 节电技术 功率因数 无功补偿 Abstract: The power factor of equipment can be used to measure the loss of energy in transmission lines. By refining the technique, we can let the power factor which is below the standard get standardized to save electricity. This article analyses the function of reactive compensation and the ways to choose capacity of compensation. It emphasizes in discussing the configuration of low voltage network and asynchronous motor’s capacity in reactive compensation. By combining with actual examples, this article also explains that using the technique of reactive compensation to improve the power factor of low voltage network and equipment has become an important measure to save electricity.
