An automatic conversion method from distribution network diagram to single-line diagram based on autocad

Abstract

The invention discloses an automatic distribution network diagram to single line diagram conversion method based on AutoCAD. Particularly, in automatic large-medium distribution conversion systems, an AutoCAD diagram designed by a distribution designer is automatically converted into a scheduling single diagram and a system diagram which are used by a dispatcher in an automatic distribution system by adopting layered conversion and layered display methods, different kinds of information of a background layer, an equipment layer and an equipment labeling layer is selectively converted and displayed according to the dispatching, operating and maintenance requirements, and a diagram topologic connection relation is automatically generated. By adopting the method, the efficiency of the automatic distribution system in project implementation and system secondary maintenance can be greatly improved, the workload of a single line diagram maintainer is greatly reduced, and a powerful technical support is provided for the distribution project implementation, dispatching, operating and maintenance.

Description

technical field [0001] The invention relates to an automatic conversion method based on an AutoCAD graphic to a single-line diagram of a distribution network, and belongs to the technical field of electric power system automation. Background technique [0002] The single-line diagram refers to a graph that expresses the structure and state of the power grid through horizontal, horizontal and vertical electrical schematic diagrams in the dispatching system. It is the most important schematic diagram for monitoring and control in the power system automation system. At the same time, in the distribution network automation system, due to the needs of overhaul and maintenance, it is often necessary to perform auxiliary analysis and positioning on the geographic background information graphics based on power grid equipment. In the design of distribution network automation engineering, system designers usually draw and mark the electrical wiring diagram and geographical backgroun...

Problems solved by technology

This drawing method has many disadvantages and hidden dangers, such as huge drawing workload, inconsistency between the drawn graphics and the actual graphics, etc.

With the development of smart grid, communication technology, computer technology, etc., the scale of distribution network automation system is getting larger and larger, and the number of monitored plants, switching stations, feeders, etc. In , the geometric quantity of graphics maintenance workload is increasing. Simply relying on manual drawing of one-line diagrams and geographic background maps often requires a lot of manpower and time, and is prone to errors.
