低压无功补偿容量的准确计算

Accurate Calculation of Low Voltage Reactive Power Compensation Capacity

现代低压无功补偿技术普遍采用电容电抗器组,其无功功率补偿容量的计算方法与传统的并联电容器补偿方式不同,目前的电气设计手册中基于纯并联电容补偿方式的计算方法及图表已不再适用,本文给出了基于电容电抗器组的无功补偿容量计算公式及换算系数,并提供新的计算图表以代替旧图表。

Capacitor reactors are widely used in modern low voltage reactive power compensation technology, the calculation method of reactive power compensation capacity is different from the traditional shunt capacitor compensation method. The calculation methods and charts based on pure parallel capacitor compensation method are no longer applicable in the current electrical design manual. The calculation formula and conversion coefficient of reactive compensation capacity based on capacitor bank are given. And the new calculations are provided to replace the old chart.
