摘 要：针对初始投资费用受限情况下的配电自动化终端布局问题，提出了一种计及初始投资费用约束的配电自动化终端优化布局方法。首先分析了考虑配电自动化终故障端辅助定位及自动隔离故障的配电网可靠性评估流程;然后在保证供电可靠性的前提下，建立了以等年值综合费用最低为目标函数，以设备投资费用为约束条件的配电自动化终端优化布局模型;最后，在IEEE RBTS BUS2算例中，采用多种群遗传算法对构建的模型进行求解，得出最优的配电自动化终端布局结果。通过与传统方法进行对比，验证了所提方法的有效性和优越性。

Abstract：In order to solve the problem of distribution automation terminal layout under the condition that the initial investment cost is limited， this paper proposes a method for optimizing the terminal layout taking into account the initial investment cost constraint. Firstly， this paper analyzes the reliability assessment process of distribution network which considering the auxiliary fault location and the automatic fault isolation of the distribution automation terminal. Secondly， based on the power supply reliability rate， an optimization model is proposed， which setting the minimum equivalent annual cost as the objective and the initial investment cost as the constraint. Finally， a multi-group genetic algorithm is used to solve the model to obtain the optimal layout results on the IEEE RBTS BUS2 example. By comparison with traditional methods， the effectiveness and superiority of the proposed method are verified.

配电自动化是提高供电可靠性，实现配电网高效经济运行的重要手段，主要是由配电主站、配电子站、配电自动化终端和通信信道组成。配电自動化终端位于配电自动化系统的基础层，负责对配电设备进行控制与调节[1]。目前关于配电自动化终端的研究主要集中在终端的电源设计[2-4]、功能实现[5-6]以及信息模块设计[7-10]等方面，针对配电终端优化布局方面的研究较少。配电终端优化布局是指根据配电网的网架结构、线路参数、用户分布，投资费用等确定馈线上终端的具体安装位置、以及安装类型。不同的终端布局方案所需的投资费用不同，对可靠性的提升效果也不同。一个科学合理的终端布局方案应该在满足供电可靠性提升要求的基础上，实现经济效益最优。……
