摘要
提出了一种基于网损功率概率分布函数的网损评估方法。据此，不但可了解网损功率的变化情况，求出网损功率的数字特征，还可以简便地算出网损电量的数值。所建立的模型较好地反映了网损问题的物理本质。
The power loss of a bulk transmission system is varied with the changes of loads.It is not easyto describe the variation of power loss and determine corresponding energy loss over a time period. A newmathematic model of losses evaluation which is based on the Probabilistic Distribution Function has been pro-pused in this paper.The varition and probabilistic characteristies of power loss,the energy loss can easilybe determined by sulving this model.The proposed model properly reflects the innate character of loss evalua-tion problems.
