无功合理补偿的容量计算与经济补偿方法

Capacity Calculation of Reasonable Reactive Power Compensation and the Economic Compensation Methods

为了作好电力用户的无功补偿工作,首先要根据无功补偿的主要目的来确定补偿无功的容量,其中包括以提高负荷功率因数、提高系统供电能力和减少线路损耗为主要目的3种情况。然后要结合实际情况采用经济的补偿方法,其中包括改用高功率因数设备和以终端补偿为主的电容器补偿。本文论述了上述两个方面的情况,并介绍了一些好的应用实例,实践表明具有良好的效果。

For improving the reactive power compensation work of the electric power consumers, first, according to the main purpose of reactive power compensation to determine capacity of reactive power compensation. These primary purposes include three situations such as improving the load power factor, improving the system power supply capacity and decreasing the line losses. Then more economical compensation method should be selected in accordance with the actual condition, such as to use equipment with higher power factor and spread local individual capacitor compensation. This article describes above two aspects and introduces some good practical application examples . The practice shows good result.
