对感性负载并联补偿电容器容量计算的研究

Research of calculating the capacity of shunt-wound compensating capacitor of inductive character load

交流负载功率因数的提高在电工技术中占有重要的地位,而感性负载常采用在负载两端并联补偿电容器来提高电路的功率因数。感性负载并联补偿电容器容量计算形式有两种途径获得,能得到相同的结果。本文拟对获得感性负载并联补偿电容器容量形式的两种方法作一些比较和讨论,而后对计算形式进行再推导,给出另一种不同的、更能反映功率因数本质的计算形式。

It is a key content about improving alternating current power-factor in electro-technology, and shunt-wound compensating capacitor is the common method used to improve power-factor for inductive character load circuit. There are two different ways to calculate the capacity of shunt-wound compensating capacitor of inductive character load, and they result in the same conclusion. Comparing and discussion of the two ways are given in this paper, then giving a deduction about the calculating method to achieve a different method which can present the essence of power-factor better.
