摘　　要：对输配电网损在分布式电源接入下的相关影响因素进行分析,在合理的约束条件下,建立分布式电源接入输配电网的数学模型,分析表明分布式电源的接入对输配电网损具有重要影响性,且主要受分布式电源接入位置、运行方式和相对负荷的分布式电源容量三个因素的影响:在合适的功率因数下,增加分布式电源输出的容量可有效减少输电线的有功损耗,且分布式电源输出的容量在负荷容量的2倍以下为宜;分布式电源以滞后功率因数方式运行,效果要优于以超前功率因数运行;分布式电源配置在输电线末端、邻近负荷位置可显著的减少输电线的有功损耗。The related influencing factors of transmission and distribution network loss are analyzed under distributed power supply access. Under reasonable constraints, the mathematical model of distributed power supply access to transmission and distribution network is established. The analysis shows that the access of distributed generation has an important influence on the transmission and distribution network loss, and it is mainly affected by three factors: access location, operation mode and relative load capacity of distributed power supply: At the appropriate power factor, increasing the output capacity of distributed power supplies can effectively reduce the active power loss of transmission lines, and the output capacity of distributed power should be less than 2 times the load capacity;It is better to run in the way of lagging power factor than in the way of leading power factor;Distributed power supply configured at the end of the transmission line and close to the load position is propitious to reduce the active power loss of the transmission line.
