摘　　要：提出采用利用系数法计算供电负荷的简化方法,采用这个方法常常可以将整个计算过程从几小时缩短到几分钟,其应用场合比较普遍,具有工程设计所需要的精度。大量实例证明,简化方法对精确法计算负荷的偏差在±10%以内的概率接近100%。最后将这种简化方法与新二项式法进行比较,互相印证,相对偏差很小。A simplified method is proposed to calculate power supply loads based on utilization coefficient method.With this method,the entire process of calculation can be shortened from hours to minutes.This method is widely applied and guarantees the precision required for engineering design.Numerous cases have proved that,with the simplified method,the probability for limiting the deviation in load calculation to±10%of the precision method is close to 100%.Finally,such simplified method is compared with the new binominal method.The methods corroborate each other and the relative deviation is very small.
