Automatic single-line diagram generation of distribution network with rings based on GA

This paper proposes a new single line diagram automatic generation method for distribution network with ring based on genetic algorithm. The method can eliminate the edge crossing, avoid components overlap and keep the layout elegant. To achieve the above goals, the none-edge crossing model is brought up and a multi-objective function is established. The solution of the objective function is acquired by utilizing genetic algorithm and considering the characteristics of the single-line diagram. The test of the method shows that the convergence time is less 2 seconds than layout of the diagram is graceful, both of which meet the daily operation requirement of electric power system department.
