Abstract

The method of power factor calculation under non-sinusoidal conditions is presented in the paper. The proposed method is based on the existing relationships between the components of apparent power under non-sinusoidal conditions. The equation for determination of total power factor under non-sinusoidal conditions is obtained and proved. This equation allows the harmonics from power source and connected load to be taken into account during calculation of the total power factor. A mathematical model of power supply system with harmonic distortions both from source and load side is developed for validation of the obtained equation. On the base of the modeling results the regularities that reflects the dependence of total power factor components on the internal impedance of power source and the correlation between rated powers of the existing in some point linear and non-linear loads. In such case the developed method and obtained equation is reasonable to use for the assessment of the influence of some active, passive or hybrid harmonic correction device on the total power factor components under non-sinusoidal conditions.

非正弦条件下功率因数的计算方法

本文给出了非正弦条件下功率因数的计算方法。该方法基于非正弦条件下视在功率各分量之间存在的关系。得到并证明了非正弦条件下总功率因数的确定公式。该方程允许在计算总功率因数时考虑来自电源和连接负载的谐波。建立了电源侧和负载侧均存在谐波畸变的供电系统的数学模型，对所得方程进行了验证。在建模结果的基础上，得出了总功率因数分量对电源内部阻抗的依赖关系和某一点线性和非线性负载额定功率之间的相关性的规律。在这种情况下，所开发的方法和得到的方程可以合理地用于评估一些有源、无源或混合谐波校正装置在非正弦条件下对总功率因数分量的影响。
