摘要
为了将配电馈线的地理接线图转换为电气接线图,建立了基于图论的配电网模型。根据空间位置和所含节点数目对分支进行分级,将一条馈线分解成由若干分支构成的集合。在电气接线图上,遵循将偶数级分支水平放置,将奇数级分支垂直放置,并注意确保各个分支的相对走向不变的原则,按照分支级数由小到大的顺序每次添加一条分支,若产生交叉或重叠则采取水平或垂直一维局部拉伸平移法来消除,从而根据馈线的地理接线图逐步生成了电气接线图。结合实例详细说明了所提出方法的基本原理,结果表明该方法可行。
In order to convert GIS based feeder maps into electric diagrams, a distribution network model based on the graph theory is developed. The branches are graded according to their position and the number of nodes on them. A feeder line consists of many branches of different grades. On the electric diagram, the even grade braches are drawn horizontally while the odd ones are drawn vertically, with the relative directions of the branches remaining unchanged. At each step, only one branch is added into the diagram in accordance with the order from low to high grades. Should an intersection or an overlap occur, a method of horizontal or vertical extension and translation will be used to remedy this situation. Gradually the electric diagram comes into being according to the GIS based feeder maps. Examples are given to illustrate the basic principle of the proposed method in detail. The results obtained indicate the feasibility of this method.
