Embodiment Construction

[0029] A method for calculating the priority of regional distribution network construction based on the unit system, comprising the following steps:

[0030] Step 1, such as figure 1 As shown, according to the regional detailed planning and the forecast results of the long-term annual load, the power supply range of the substation and the target grid structure are clarified, and the regional distribution network to be constructed is divided into several power supply units by referring to the unit division principle, and then the power supply unit is divided into several power supply units according to the corresponding power supply unit Quality requirements Build the form of the target network structure, carry out the intermediate transition year and the planning of the network structure in the near future according to the target network structure, and obtain the project table in units of groups; the division principles of the units include:

[0031] a. Each power supply unit ...

Abstract

The invention discloses a method for calculating the construction priority of a regional distribution network based on a unit system, which includes the following steps: S1, dividing a regional distribution network to be constructed into a plurality of power supply units; S2, establishing an importance coefficient index system and a construction demand coefficient index system for each power supply unit; S3, determining the importance coefficient index weight and the construction demand coefficient index weight of each power supply unit through AHP (Analytic Hierarchy Process), and using a membership function to calculate the importance coefficient index score and the construction demand coefficient index score of each power supply unit; S4, calculating the importance coefficient I and theconstruction demand coefficient D of each power supply unit according to the index weights and the index scores; and S5, calculating the construction priority coefficient P of each power supply unitaccording to formulas. Based on the idea of unit planning, an evaluation system of power supply units is established with units as objects to quantitatively analyze the priority of each unit. The investment level of the distribution network precision construction is greatly improved.

Description

technical field [0001] The invention relates to the technical field of distribution network construction, in particular to a method for calculating the priority of regional distribution network construction based on a unit system. Background technique [0002] At present, investment in distribution network construction is allocated in a plate-based manner, which lacks scientific basis and easily leads to investment waste. Facing the new situation of distribution network development, it is necessary to optimize the investment in distribution network to improve the economic benefits of power grid enterprises. Contents of the invention [0003] The invention discloses a method for calculating the priority of regional distribution network construction based on a unit system, which can provide a scientific basis for the construction of distribution networks of power grid enterprises and improve the economic benefits of the power grid enterprises. [0004] The present invention...
