Embodiment Construction

[0020] A method for predicting the load of a power supply grid based on a geographic information system. The present invention is characterized in that it includes the following steps:

[0021] Step 1: Power supply grid drawing is based on the power geographic information system combined with grid grid planning ideas, and the power supply area is divided into several grids in the geographic map; the power supply grid division principle is mainly to realize the interconnection and mutual supply between two substations , The power supply grid can be divided into relatively independent power supply areas with self-healing potential from one to three groups of double-ring networks or single-contact power supply capabilities. The grid should include medium-voltage main lines as much as possible, and use canals, railways, and main roads. Clustering for boundaries;

[0022] Step 2: Load control regulations information and parameter settings Load the control plans collected from the munici...

Abstract

Provided is a power supply grid load predicting method based on a geographic information system. A grid planning concept is introduced based on a power geographic information system. By combining the municipal planning and construction scheme and the distribution network planning technical guideline and according to the characteristics, a power supply area is divided in a scientific and reasonable manner based on the idea of large-to-small and divide-and-rule to form a plurality of relatively independent power supply grids with clear grid structure and self-healing potential. A strong support is provided for power demand prediction, distribution network status analysis, planning project scheme drafting, planning effect evaluation and investment decision making.

Description

Technical field [0001] The invention belongs to a power grid planning system in the power industry, in particular to a distribution network planning method based on a geographic information system for power supply grid load prediction. [0002] technical background [0003] The power system is a very important subsystem of the entire national economy or energy system. The power system exists and develops to provide users with power to meet their needs. The distribution network is a component that directly faces users, so it is particularly important. . For power supply companies, reasonable distribution network planning is to find a way to save costs and meet the power supply needs and reliability of users. [0004] Distribution network planning mainly consists of power load forecasting, power supply planning and grid planning. Power grid planning is based on load forecasting and power planning, and minimizes the cost of power supply system construction on the premise of ensuring t...
