配电网络经济运行电压的分析

VOLTAGE ANALYSIS FOR ECONOMIC RUNNING OF POWER DISTRIBUTION NETWORK

负荷大小变化较大的配电网，在大负荷时升高电压，轻负荷时降低电压，可使配电网的网损降低。因此，合理调整主变压器分接头即可达到配电网降损的目的。文章通过理论分析给出对应某一负荷下，配电网经济运行电压的确定方法。

Incresed voltage in a high load and decresed voltage in a small load could decrese power losses in a power distribution network in case of a great variation of load.Therefore,taping adjustment of main transformer could decrese the power loss in the network. This article describes the way to make a power distribution network running economically in the certain load by theoretical analysis.
