Layout Design of Low Voltage Distribution Automation Terminal

为解决传统0.4 kV配电自动化终端的布局设计下,供电可靠性低的问题,设定0.4 kV配电自动化终端设备参数,计算配电自动化终端布局设计组合权重,构建配电自动化终端布局费用最小优化模型,以模型最优解为配电自动化终端布局设计结果,并通过可靠性评估的方式,完成0.4 kV配电自动化终端的布局设计。设计实例分析结果表明,该设计布局下的配电网供配电可靠性指标明显高于对照组且能降低传统布局设计下的供电线路损耗。

In order to solve the problem of low power supply reliability under the traditional 0.4 kV distribution automation terminal layout design,the 0.4 kV distribution automation terminal equipment parameters are set,the distribution automation terminal layout design combination weight is calculated,and the minimum optimization model of distribution automation terminal layout cost is constructed.The optimal solution of the model is used as the result of the layout design of the distribution automation terminal,and the layout design of the 0.4 kV distribution automation terminal is completed by means of reliability evaluation.The analysis results of the design example show that the reliability index of the power supply and distribution network under the design layout is significantly higher than that of the control group and can reduce the power supply line loss under the traditional layout design.
