Embodiment

[0091] In this embodiment, a distribution network automatic planning method oriented to solve the grid diagnosis problem is proposed, which includes the following steps:

[0092] S1: Classify the typical problems in the existing power grid. The typical problems in the power grid are divided into line problems, station area problems and other problems. Line problems include 10kV line overload, 10kV line overload, unqualified line voltage, new Load power supply needs to be met, potential safety hazards in lines, and grid structure to be improved. Problems in the station area include distribution transformer overload, distribution transformer overload, station area voltage unqualified, new load power supply needs to be met, and distribution transformer safety Hidden dangers, other problems include equipment or lines that are old and need to be replaced;

[0093] S2: Aiming at the typical problems that have been classified in S1, put forward the solution ideas in the actual planni...

Abstract

The invention discloses a distribution network automatic planning method oriented to solve the grid diagnosis problem, which includes the following steps: S1: Classify the typical problems existing in the existing power grid, and the typical problems existing in the power grid are divided into line problems, station problems District problems and other problems. Line problems mainly include 10kV line overload, 10kV line overload, line voltage unqualified, new load power supply needs to be met, line safety hazards, and grid structures to be improved. Starting from the analysis of the existing power grid, the present invention simplifies and abstracts the factors considered in the actual planning, and at the same time obtains the corresponding automatic generation scheme of the planning project with the help of calculation results of various power grids. The automatic generation scheme of the planning project is carried out through the AUTO CAD platform This is of pioneering significance for the development of auxiliary decision-making for distribution network planning.

Description

technical field [0001] The invention relates to the technical field of distribution network automatic planning, in particular to an automatic distribution network planning method oriented to solve the problem of network diagnosis. Background technique [0002] With the acceleration of new urbanization and the rapid development of distributed power sources, micro-grids, and electric vehicles, it will inevitably bring about rapid growth of distribution network loads, new changes in network functions and forms, and put forward more requirements for distribution network planning. high demands. However, the planning of my country's urban distribution network is still mainly completed by the experience of planners, resulting in high subjectivity of planning schemes, and it is difficult to quantify and compare different schemes. From the perspective of the long-term development of the power grid, this planning method also makes the planning of the distribution network unable to ac...
