Distribution network planning is a multi-goal and multi-restricted problem that involves the geographical condition of power line route, constructing and maintenance expenses, power line losses, power flow and security constraint. Computer aided planning is an important studying direction now. However, automatic line routing can not be made now. A model is advanced in this paper to minimize the work of planner and to simplify the network planning procedure. In this paper, an improved particle swarm optimization (PSO) is used to escape the locally point by adopting the probability distribution feature and controlling the flying speed automatically. By using this method in Jinan power network, found that the speed of network-planning can be improved by adopting the improved PSO and geographical feature pretreatment. (7 pages)
