1、无功补偿详细的容量确定计算方法-补偿容量的确定可以根据负荷的最大功率、补偿前的功率因数及 要求补偿后达到的功率因数，用下式计算确定：Q=a*P*(tanitan2)式中：Q 所需补偿的总无功功率，kvar;a平均负荷系数，取 0.70.8;P 用户最大负荷，kW;tan1补偿前平均功率因数角tan2补偿后平均功率因数角或 Q=a*P*qq 补偿率，kvar/kW(可从附表中查取)附表：每 kW 负荷所需无功补偿率值查取表COS10.800.810.820.83 0.840.500.510.520.530.540.550.560.570.580.590.600.610.9810.9390.890
