Computer-aided planning method based on three-layer planning model of power distribution network transition scheme

Abstract

The invention discloses a computer-aided planning method based on a three-layer planning model of a power distribution network transition scheme, which adopts Matlab software as an operation platform,and comprises the following specific steps: 1, carrying out planning premise work, deeply investigating the site, the current situation and planning station and location, collecting data and collecting information; determining the boundary of the three-layer planning model of the power distribution network transition scheme for modeling and planning requirements; 2, creating and calculating an upper-layer planning model; 3, creating and calculating a middle-level planning model; 4, creating and calculating a lower-layer planning model; 5, integrating a transition net rack scheme; and establishing a transition net rack planning scheme in the planning stage. According to the method, a scientific, efficient, reasonable and ordered planning process can be provided for transition net rack planning, and safe, reliable, economical and reasonable transition from a power distribution network rack with increasingly large scale and increasingly complex elements to a target net rack is promoted.

Description

Technical field [0001] The invention relates to the technical field of computer-assisted distribution network planning, and in particular to a computer-assisted planning method based on a three-tier planning model of a distribution network transition scheme. Background technique [0002] The lean level of distribution network planning continues to improve, and scientific and efficient distribution network transition grid scheme planning is increasingly important. The overall principle of the distribution network transition plan planning is: on the basis of the current grid structure, based on the load forecast results, in conjunction with the development and construction sequence, on the one hand, temporary or fundamental reinforcement measures for weak links are taken, on the other hand, combined with the long-term perspective The grid connection scheme designs different stages of connection forms, and finally realizes the gradual transition to the long-term goal grid. How to c...
