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.

1 Introduction

Distribution network planning is a huge project involving wide range and large volume of data. Distribution network planning needs to collect a large number of grid historical data and urban development-related data, also needs to have an in-depth understanding of the status quo power grid and have a more comprehensive understanding of the future development of the city. At present, network planning is still using artificial methods of calculation, not only laborious and time-consuming but also difficult to grasp the accuracy of the data processing. Totally depending on the experience of artificial planning for the future of the electricity network cannot meet the requirements of modern network planning, in view of this, we research and develop “compute decision-making support system for power distribution network planning based on GIS”.
