净水厂中低压无功补偿的相关参数计算

Calculation of Relevant Parameters of Low Voltage Reactive Power Compensation in Water Plant

现代净水厂中普遍采用电容电抗器组的形式在低压侧进行集中补偿。工程设计中常常忽略串联电抗器及电容器实际运行电压的计算,将电容电抗器组的额定容量作为实际输出容量,导致补偿后的功率因数不满足国家、地区标准的要求。针对串联电抗器及电容器额定电压的选择,对实际无功输出容量产生的影响进行分析,可为实际工程设计提供参考。

In modern water plants,the capacitor reactor bank is widely used for centralized compensation at the low voltage side.In engineering design,the calculation of series reactor and actual operating voltage of capacitor is often ignored,and the rated capacity of capacitor reactor bank is taken as the actual output capacity,resulting in the power factor after compensation not meeting the national or regional requirements.The influence of series reactor and rated voltage selection of capacitor on actual output capacity was analyzed.It can provide references for actual engineering design.
