The invention provides a distribution network transformation and construction analyzing and planning system, which comprises a stage control subsystem, a mode control subsystem, a method control subsystem and a technology control subsystem. The distribution network transformation and construction analyzing and planning system dynamically controls the stage of management planning through the stage control subsystem, controls the transformation and construction mode through the mode control subsystem controls the specific procedures of the planning through the method control subsystem, and select the appropriate technical model in the planning through the technology control subsystem to form a closed-loop whole-process planning management. By the distribution network transformation and construction analyzing and planning system, the planning of design of the distribution network is led and proceeded in order. Urban and rural overall development and supply are guaranteed. The system is unified in standard, safe, economic, intelligent, environment-friendly, upgraded, and innovative.
