Computer decision-making support system for power distribution network planning based on geographical information system

The structure of computer decision-making support system for power distribution network planning is introduced. The data getting and models of system are described. Distribution modeling can be done in the different kinds of data preparation. According to the differences of system´s functions, the department of network planning and the department of network alteration are briefly introduced. The system is conveniently, result is direct perception, and it contains the main work of network planning and alteration. This system has been successfully applied in some urban power networks. The result show that it can not only optimize the planning results of urban power distribution network considering many complicated factor, but also reduce the work of computation, analysis and graphic drawing.
