摘　　要：安装分段开关和配电自动化终端能够显著提高配电网的供电可靠性,但目前的研究中,分段开关的候选位置通常只在主馈线上,忽略了分支线路上安装分段开关与配电自动化终端对可靠性的影响。在此背景下,研究了考虑分支线路的配电网分段开关与自动化终端优化布置策略。首先,介绍了配电网不同故障场景下用户停电时间的计算方法;其次,建立了以经济性最优为目标的分段开关与配电自动化终端最优布置模型,该模型被建立为混合整数线性规划模型,可以利用商业求解器CPLEX快速求解;最后,通过算例分析,验证了所提方法的有效性和实用性。The installation of the sectional switch and the distribution automation terminal can significantly improve the power supply reliability of the distribution network.In the current research,the candidate position of the sectional switch is usually only on the main feeder line,and the impact on reliability of the sectional switch and distribution automation terminal are ignored.In this paper,the optimization configuration strategy considering the branch line of the distribution network segmentation switch and automation terminal is studied.Firstly,the calculation method of user power outage time in different fault scenarios of distribution network is introduced.Secondly,the optimal configuration model of segmentation switch and distribution automation terminal aiming at economic optimization is established.The model is established as a mixed integer linear programming model,which can be solved quickly by the commercial solver CPLEX.Finally,the validity and practicability of the proposed method are verified by a case study.
