区域电网系统单线图将变电站接线图与站间线路连接在同一个平面展现。以110kV地区电网为例,首先利用其220kV变电站为电网枢纽,辐射状连接110kV变电站的特征对全网进行分区。提出了使区块内变电站数量较均匀,区块间的联络线尽可能少的分区方法。对变电站内、外模型图形进行设计。区块内布局布线问题转化为2个无耦合的顺序阶段求解：以线路交叉数和线路曼哈顿距离的加权最小为目标函数,运用改进的粒子群算法进行变电站外模型元件的优化布局,然后进行走线;若变电站同母线出线位置可调,则内模型图形可进行站内出线位置调整,否则可直接嵌入到前阶段成果外模型图形的方框内。

The regional power grid system single-line diagram is one in which the lines between substations and the substation internal primary single-line diagrams are shown together on one and the same plane.Take the 110 kV prefectural power grid as an example.A grid dividing method requiring rather uniform number of substations within a section and the least possible line connections between section blocks is proposed by taking advantage of the 220 kV substations as the hub of the radially formed 110 kV substation group to divide the prefectural grid into sub-grids.A design is made for the internal and external substation diagrams of the substation layout/routing inside a sub-grid,and the initial layout/routing problem is converted to a two-stage problem in sequence but without coupling.The first stage is layout and routing optimization based on the external substation diagram model,with the least intersection number and Manhattan distance of lines as the objective function.An improved particle swarm optimization algorithm is designed for assembling of the external substation rectangle,followed by a carefully designed algorithm for line routing.If the positions of outgoing lines of the substation from the same bus are adjustable,then the instation outgoing line adjustment of the internal model diagram can be performed.Otherwise the entire system diagram is just the result of the first stage with the box directly embedded in the single-line diagram of substation.
