针对传统配电网规范化不足、无序发展等弊端，结合工程实践研究了网格化供电模式，建立了分析计算平台，通过配置上级变电站供电区域及供区网格规模大小，解决了网格之间及网格内部的联络问题。提出了网格之间以变电站定向联络为主干，网格内部以线路分段之间联络为依托的“联络组合”理念，并将研究成果应用于复杂城市配电网建设改造中。实践证明，“联络组合”不仅优化了变电站联络和配电网的供电能力，提高了设备利用效率，还增强了配电网对上级电网的支撑能力。

In allusion to such drawbacks of traditional distribution networks as insufficient standardization and disorderly development, based on engineering practice the mesh-networking mode for power supply is researched and a platform for the analysis and calculation for this power supply mode is built. Through configuring the power supply area of upper level substation and the sizes of power supply meshes, the interconnection among meshes and the connection inside the mesh can be solved. An idea of connecting combination, which takes the directional tie lines among substations as backbone lines and the connection combination among line sections inside the mesh as props, is proposed and the research results are applied in the construction and renovation of complex urban distribution networks. Practical applications show that the connection combination not only can optimize the interconnections among substations as well as the power supply capability of substations and improve the equipment utilization efficiency, but also can enhance the supporting capacity of distribution networks to upper level power grid.
