并联补偿内参数变化对补偿定量影响分析

The influence of the internal-parameters in the parallel connection compensation on the compensation quantity

在交流电路中,用电设备大多属感性负载,因此,功率因素不高的根本原因是由于感性负载的存在.提高负载的功率因素能使发、配电设备得到充分利用,同时能减少线路及发、配电设备内部的功率损失,用适当的电容器和负载并联,可以提高功率因素.由于感性负载和并联电容内阻抗参数随着它们取值大小而变化,直接影响着功率因素值.文章通过容抗XC和容电阻RC随电容C的变化关系,分析了并联补偿内参数变化对功率因素的定量影响,并提出了修正措施.

Most of the electrical equipments in the alternating electrical c ir cuits belong to the inductive load and such loads can result in the low power. T he increase of the load of power factor makes the equipments for producing and s ending electricity efficient and simultaneously, decreases the inner-power los ses of the circuits and equipments. The power can be improved by connecting the appropriate capacitor with the load. The inductive load and the internal-impen dence parameters in the connective electric capacity vary along with their data and thus directly influence the power. By analyzing how the electric capacity ch anges along with the capacity impendence Xc and resistance Rc, this article disc usses the way the internal-parameters in the parallel connection compensation influence the power factor quantity, and it also proposes the solutions to the i nfluence.
