Problems solved by technology
At present, the domestic distribution network planning software can exchange data with the grid GIS platform through the CIM file, which cannot be simplified, resulting in only display and analysis for the station building and the connection relationship of each station building, but for the equipment in the station building and The topological structure cannot be displayed and analyzed, which brings great deviation to the analysis and calculation results of the distribution network planning software's subsequent power grid structure

Embodiment Construction
[0041] Such as figure 1 Shown is the method flowchart of the method of the present invention: the method for simplifying the geographical model of the power grid to the distribution network planning business model provided by the present invention includes the following steps:
[0042] S1. Divide the grid equipment into in-station equipment and off-station equipment, and obtain the attribute information of all in-station equipment and off-station equipment; divide the grid equipment into off-station equipment and in-station equipment according to the relative position of the grid equipment and the station building; at the same time, The equipment outside the station is further divided into node equipment (including towers and cable terminals, etc.), branch equipment (including cable sections and overhead wires, etc.) and auxiliary equipment (including distribution transformers and pole-mounted switches, etc.);
[0043] S2. According to the attribute information of the off-site...

The invention discloses a method for simplification from a geographic model of a power grid to a distribution network planning business model, which includes dividing power grid equipment into in-station equipment and out-of-station equipment and obtaining attribute information of all equipment; The equipment is simplified to obtain the simplified model of the equipment outside the station or inside the station; the simplified model of the equipment outside the station and the simplified model of the equipment inside the station are connected to obtain the final simplified model of the power grid. The present invention simplifies the equipment inside and outside the station, and connects the simplified models to obtain the simplified power grid model. Therefore, the method of the present invention can simplify the equipment outside the station and inside the station respectively, so as to provide future The analysis provides the basic data model, and the simplification effect is good, and the simplified model is intuitive and accurate.
Description
technical field [0001] The invention specifically relates to a method for simplification from a geographic model of a power grid to a distribution network planning business model. Background technique [0002] With the development of national economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source in people's daily production and life, bringing endless convenience to people's production and life. [0003] The distribution network is composed of multiple station buildings, overhead lines, cables, towers, distribution transformers, isolating switches, reactive power compensation capacitors and some auxiliary facilities, etc., and plays an important role in the distribution of electric energy in the power network. The key point between grid equipment is the grid topology relationship, that is, the power supply connection relationship between the power supply, the downstream distribution transfo...
