摘要
The automatic generation of the electrical diagram for a distribution network is a complex optimization problem. The nature of this process is to determine the relative positions of equipment of the distribution network in a 2-D plane. Based on a simplified hierarchical model, an automatic drawing algorithm is proposed to automatically generate the electrical diagram. The algorithm solves this problem by decomposing it into three steps, namely, preliminary layout, framework routing and complete drawing. The preliminary layout is obtained with gravitation-repulsion model. The power station drawing is completed through equipment classification and comparison of each outlet line's dip angle. The routing priority is used to ensure there is no overlapping and crossing of routing. The overall automatic generation of the electrical diagram can then be obtained with respect to its original integrated topology structure. Finally, a practical case study of a city's distribution network is given to show the effectiveness of the method and the automatic layout algorithm.
