Problems solved by technology

The process of carrying out the grid planning of medium-voltage distribution network is mostly based on personal experience or temporary creativity. There is no fixed and systematic working method, the relevant work procedures are not reproducible, and the relevant work results are unstable. not traceable
At the same time, the discussion and solidification of the original medium-voltage distribution network grid planning scheme are mainly based on the compilation of project tables and drawing of CAD electrical wiring diagrams. There is no simple and classified way to clearly display the current status of grid lines and planning target network by using geographical layout diagrams. rack conversion process method

Abstract

The invention relates to the technical field of voltage distribution networks, in particular to a medium-voltage distribution network grid planning method, which forms a standard work flow of the medium-voltage distribution network grid planning method, so that the planning work is reproducible, and the work result is stable and traceable. The method is suitable for a power supply enterprise to scientifically, quickly and effectively complete grid planning work of the medium-voltage distribution network in a complex region, improves the systematicness, practicability and operability of the distribution network planning work, is suitable for a medium-voltage distribution network planning quick short-circuiting board, and effectively improves the working quality.

Description

technical field [0001] The invention relates to the technical field of voltage distribution network, and more specifically, to a method for grid planning of a medium-voltage distribution network. Background technique [0002] The grid planning of the medium voltage distribution network is to divide the power supply area of ​​the medium voltage distribution network into several independent grids, and plan several sets of independent medium voltage feeder groups for each grid to supply power, so that the A relatively independent medium-voltage distribution network planning method for power supply capacity improvement and current situation problem solving. In the past, there was no unified method for the grid planning of the medium-voltage distribution network. The so-called steps were only the planning outline. There is no standard process for how to do it. The process of carrying out the grid planning of medium-voltage distribution network is mostly based on personal experi...
