【摘要】：配電網(wǎng)饋線單線圖有時(shí)需要根據(jù)拓?fù)溥B接關(guān)系生成,既要獲得良好布局效果又要滿足成圖的快速性,為此提出一種基于改進(jìn)引力—斥力算法的分塊布局方法。首先,確定配電網(wǎng)主干線,基于主干線對(duì)電網(wǎng)進(jìn)行分塊布局,以降低維度、提高計(jì)算效率;其次,塊內(nèi)布局時(shí)對(duì)引力—斥力算法加以改進(jìn),即根據(jù)深度優(yōu)化分支節(jié)點(diǎn)并改進(jìn)主干線節(jié)點(diǎn)質(zhì)量與距離,使線路分布均勻、避免與主干線過近及減少交叉;最后,為了避免相鄰分塊的分支交叉,對(duì)每個(gè)分塊添加虛擬節(jié)點(diǎn),優(yōu)化邊界分支布局。對(duì)算法優(yōu)化前后圖形效果進(jìn)行了對(duì)比,并給出圖形分塊對(duì)時(shí)間的影響,仿真結(jié)果表明饋線單線圖布局清晰、交叉點(diǎn)少,算法計(jì)算時(shí)間短,能夠滿足用戶需求。
[Abstract]:The single line diagram of feeder line in distribution network sometimes needs to be generated according to the topological connection relation. It is necessary to obtain good layout effect as well as to satisfy the speediness of mapping. For this reason, a block layout method based on the improved Gravity-Repulsive Force algorithm is proposed. In order to reduce the dimension and improve the calculation efficiency, the main line of distribution network is divided into blocks based on the main line. Secondly, the gravity-repulsion algorithm is improved when the distribution network is arranged within the block. That is to optimize the branch node according to the depth and improve the quality and distance of the main line node, so that the line distribution is uniform, avoid too close to the main line and reduce the crossover. Finally, in order to avoid the branch crossing of adjacent blocks, we add virtual nodes to each block. Optimization of boundary branch layout. The effect of graphics before and after optimization is compared. The simulation results show that the layout of feeder single line diagram is clear, the intersection points are few, and the calculation time of algorithm is short. Able to meet the needs of users.
