    Abstract:The binomial method used for computing power supply loads is described. In the new binomial,the first item is to compute the average load of electrical equipment within the scope of computation,while the other item is to compute the additional load CP5 increased when 5 pieces of electrical equipment with the maximum capacity are put into operation within the scope of computation. For the calculated coefficient C is increased or decreased with the changes in utilization coefficient within the scope of computation,it is different from those binomial method used previously. C is a univalent function of Kl,C value in C - Kl Table has 3 significant digits,the table lookup precision is high and the scope of changes in C value is extremely small(0. 129 ~ 0. 302),so the computation precision of the new binomial method is significantly high.
    Key words:new binomial method;utilization coefficient Kl;demand coefficient Kx;correction coefficient α;comprehensive coefficient Kz;calculated coefficient C;calculated of active power Pj s;total power Pn of n pieces of equipment;the maximum power P5 of 5 pieces of equipment
    摘 要:介绍计算供电负荷的新二项式法。新二项式中的第一项是计算范围内用电设备的平均负荷,而另一项是计算范围内5台容量最大的用电设备投入运行时增加的附加负荷CP5。由于计算系数C随计算范围内利用系数Kl的大小变化而变化,因此它不同于过去所用的二项式法。由于C是Kl的单值函数,C - Kl表中的C值有3位有效数字,新二项式法的查表精度高,而且C值的变化范围很小(0. 129 ~ 0. 302),所以新二项式法的计算精度很高。
