摘　　要：线损是电力系统经济运行的重要指标,也是反映系统运行状态的基础参数。基于电路理论,针对配电网络线路损耗与负荷之间的关系进行研究,分析了负荷变化对辐射型线路线损的影响,推导出线损变化率与负荷变化率的解析表达式,构建了线损线性分析、计算的理论基础,最后通过算例验证了理论分析的正确性。Transmission Loss is an important index of economic operation of the power system, but also reflects the oper- ating status of the system. Based on circuit theory, this paper studies the relationship between the transmission loss and load of distribution network, and the influence of load changes to radiation line has been analyzed. The function formula between transmission loss rate and load rate is derived, the basic theory of linear analysis and calculation for transmission loss has been built up. It is correct and effective, verified by calculation and analysis of the standard system.
