摘　　要：提出了两种预估输电系统网损的方法 ,一种方法根据系统总发电功率概率分布函数预估网损功率概率分布函数及网损电量 ;另一种根据系统总发电功率的数学期望预估网损功率的数学期望及网损电量 。In this paper,two methods to predication the power and energy loss are proposed,one is through the probabilistic distribution function of the total generator power;the other is through the expected value of the total generator power,and the validness of the two methods are testified in a real system.
