无功补偿容量计算方法及表

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 0.840.500.510.520.530.540.550.560.570.580.590.600.610.9810.9390.8900.8190.8080.7660.7280.6910.6550.6180.5830.549COS20.85 0.860.870.880.890.900.910.920.930.940.950.961.1661.192 1.2191.2461.2761.305 1.3381.3681.4041.4421.1341.160 1.1871.2141.2441.273 1.3061.3361.3721.4101.075 1.1011.1281.1551.1851.217 1.2471.2771.3131.3511.0341.060 1.0871.1141.1441.173 1.1201.2061.2361.2720.9931.019 1.0461.0751.1031.133 1.1651.1951.2311.2691.0081.035 1.060 1.0861.117 1.1380.9660.933 1.018 1.0441.070 1.1060.9170.945 0.969 0.9951.021 1.0470.8760.903 0.928 0.9540.980 1.0060.835 0.8620.887 0.9130.939 0.9651.8.920.7930.820 0.815 0.8710.897(30.9510.9771.0041.0311.0611.090 1.1231.1531.1891.2270.755 0.7820.807 0.8290.859 0.8850.913 0.9390.9660.9911.0231.052 1.0851.1151.1511.1890.7180.745 0.770 0.7960.822 0.8460.6820.709 0.734 0.7600.786 0.8120.645 0.6720.697 0.7230.749 0.7750.6100.637 0.662 0.6880.714 0.7400.5760.603 0.628 0.6540.680 0.7060.876 0.9020.9290.9560.9861.015 1.0481.0781.1141.5200.840 0.8660.8930.9200.9500.979 1.0121.0421.0781.1160.803 0.8290.8560.8830.9130.942 0.9751.0051.0411.0790.768 0.7940.8210.8480.8780.905 0.9400.9701.0061.0440.734 0.7600.7870.8410.8440.873 0.9060.9360.9721.0100.620.630.640.5150.4810.4500.5470.560 0.5940.6200.640 0.6720.5080.535 0.560 0.5860.612 0.6380.4770.504 0.529 0.5550.581 0.6070.700 0.7260.7530.7800.8100.839 0.8720.9020.9380.9740.666 0.6920.7190.7460.7760.805 0.8380.8680.9040.9420.635 0.6610.6880.7150.7450.774 0.8070.8370.8730.911COS10.800.810.820.83 0.840.650.660.670.680.690.700.710.720.730.740.750.760.770.780.790.800.810.820.830.840.850.85 0.86cos20.870.880.890.900.910.920.930.940.950.960.602 0.6280.6550.6820.7120.741 0.7740.8040.8400.8780.573 0.5990.6260.6540.6830.712 0.7450.7750.8110.8490.542 0.5660.5950.6220.6520.681 0.7140.7440.7800.8180.512 0.5380.5650.5940.6220.651 0.6840.7170.7500.7880.482 0.5080.5350.5620.5920.621 0.6540.6830.7200.7580.455 0.4810.5080.5350.5650.594 0.6270.6570.6930.7310.426 0.4520.4790.5060.5360.565 0.5980.6280.6640.7200.397 0.4250.4500.4770.5070.536 0.5690.5990.6350.6730.370 0.3960.4230.4500.4800.509 0.5420.5720.6080.6460.342 0.3680.3950.4250.452)0.481 0.5140.5460.5800.6180.316 0.3420.3690.3960.4260.455 0.4880.5180.5540.5920.288 0.3160.3410.3680.3980.427 0.4600.4920.5260.5630.263 0.2890.3160.3430.373)0.402 0.4350.4650.5010.5390.237 0.2630.2900.3170.3470.376 0.4090.4390.4750.5130.209 0.2350.2620.2890.3190.348 0.3810.4110.4470.4850.183 0.2100.2380.2660.2940.326 0.3550.3870.4210.4580.1570.1800.2120.2400.2680.298 0.3290.3610.3950.4320.105 0.1320.1600.1880.2160.246 0.2770.3090.3430.3800.079 0.1060.1340.1620.1900.220 0.2510.2830.3170.3540.053 0.0800.1070.1350.1640.194 0.2250.2570.2910.3280.4170.3860.3570.3270.2970.2700.2410.2120.1850.1570.1310.1030.0780.0520.0240.444 0.4710.496 0.5220.548 0.5740.415 0.4420.467 0.4930.519 0.5450.384 0.4110.436 0.4620.488 0.5140.354 0.3810.406 0.4320.458 0.4840.324 0.3510.376 0.4020.428 0.4540.2970.323 0.349 0.3750.401 0.4270.2680.295 0.320 0.3460.372 0.3980.2390.266 0.291 0.3170.343 0.3710.2120.239 0.264 0.2900.316 0.3420.184 0.2110.236 0.2620.288 0.3150.1580.185 0.210 0.2360.262 0.2880.1300.157 0.182 0.2080.234 0.2600.105 0.1320.157 0.1830.209 0.2350.0790.106 0.131 0.1570.183 0.2090.051 0.0780.103 0.1290.155 0.1810.026 0.0520.078 0.1040.130 0.1570.0260.052 0.0780.104 0.1310.026 0.0520.078 0.1040.1310.1580.1860.2130.2420.272 0.3030.3350.3690.4060.0260.052 0.0790.026 0.0530.026
