功率因数计量方法对无功补偿容量的影响

改善功率因数是电力系统提高电能质量的重要手段之一，但装设电力电容器进行无功补偿的容量却应根据不同的考核方法和不同的负荷性质而定，否则，不但无法有效提高功率因素，而且还会适得其反，文章针对目前国内不同地区并存的三种功率因数计量和考核方法，根据不同用户，不同负荷性质提供了无功补偿容量的三种计算原理和计算公式，并举例说明，以确定适当的无功补偿容量。

The Influence of cos(ψ) Measuring to Var Remedy

Enhancing power factor is one of the important means to raise the quality of power energy. But the fixing of power capacitor to increase reactive power complimentary should be in accordance with different test methods and different load characters. Otherwise,the result would be on the contrary. In view of the three existing power factor measurements and test methods in various parts of the country, this article offers three measuring theories and measuring formulas for reactive power complimentary capacity in accordance with different customers and load characters.Examples have been cited to determine proper reactive power complimentary capacity.
