摘　　要：引起线损率变化的原因是多方面的,但在一定时期内,网络结构和运行方式可能没有较大变化,在此条件下,通过对网络的简化,建立数学模型,找出线损率随用电负荷变化的规律,可对线损率的预测及分析提供重要参考。There are a lot of factors lead to line-loss rate variation, meanwhile the structure and operation mode of network may haven't any major change at a definite period. In this case, through simplify the network and set up a mathematical model, we can find out the rules that guiding line-loss rate varies with load. This can be used as an important reference for line-loss prediction and analysis. 
