Automatic Generation of Transmission Network Single-line Power Flow Diagram for Dispatching Large Screen DisplayPart Two Automatic Routing

调度大屏输电网潮流图布线阶段除了考虑线路的走线外,还要考虑线路名称、断路器、实时潮流量以及显示各类设备状态挂牌等局部布置,从而突出其可读性。文中介绍了顺序走线、优化布线2个阶段的自动布线步骤。顺序走线包括廊道宽度设置,变电站出线布置,线路顺序走线,断路器图元、线路名称、潮流、设备状态挂牌标识布置及调整4个步骤;优化布线包括拆线重布线、整体均匀走线调整2个步骤。在拆线重布线阶段,提出了保护性拆线和非保护性拆线2类拆线策略,作为搜索引擎优化算法的策略库,来最小化布线线路的交叉。所提出的布线算法考虑了较深入的细节,在实际工程应用中取得了良好的效果。

Apart from considering the routing of power lines, automatic routing of dispatching large screen for transmission network power flow diagram should be also added the name of lines, circuit breakers, real-time power flow values, as well as tag plate displaying status of main equipments, etc. , in order to highlight the readability of the whole diagram. A two phases solution for automatic routing, namely, sequential routing and optimal routing is proposed. Sequential routing includes corridor width assignment and regulation, outgoing lines placement surround the substation, lines routing according to discrete horizontal and vertical order of the position of substations, auxiliary placement as mentioned above. Optimal routing includes dismissing together with re-routing, integrated uniform placement adjustment. Two strategy categories, in name as protected dismissing and un-protected dismissing, compose the strategy storage of the search engines optimization method, in order to minimize the numbers of intersection of lines. Therefore, a good result in practical engineering applications has been achieved, due to the very detailed design of the automatic routing algorithm
