Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] The establishment method of distribution network power supply mode library of the present invention, it comprises the following steps:

[0021] 1) As shown in Table 1, according to the range of load density σ of A+~E power supply areas, classify the power supply areas in a certain area. Among them, the load density σ of the power supply area is:

[0022]

[0023] In the formula, the 110 kV and 66 kV special line loads are deducted from the electricity consumption, and the effective power supply area is not less than 5 square kilometers.

[0024] Table 1 Classification of power supply areas

[0025]

[0026] 2) According to the division of the power supply area of ​​a certain area in step 1), the area can be further divided according to the functions, which can be divided into administrative areas, commercial areas, residential areas, de...

Abstract

The invention relates to a method for establishing a power supply mode bank of a power distribution network. The method comprises the following steps of classifying power supply areas in some region according to the range of load density sigma of power supply areas in types of ranging from A+ to E; establishing a basic module group of power supply modes, wherein the basic module group comprises a power grid power supply module group, a power source access module group, a user access module group and a power distribution automation module group; further dividing the region according to functions based on division of the power supply areas in some region; determining a plurality of typical power supply areas according to the division result; selecting the power grid power supply module group, the power source access module group, the user access module group and the power distribution automation module group which are suitable for regional development from the established basic module group, and establishing corresponding power supply modes of the power distribution network for the plurality of typical power supply areas, wherein the power supply modes of the power distribution network form the power supply mode bank of the power distribution network. The method can be widely applied to the process of power supply mode establishment in some area.

Description

technical field [0001] The invention relates to a method for establishing a power supply model library, in particular to a method for establishing a distribution network power supply model library. Background technique [0002] The distribution network is an important part of the power grid. It is directly oriented to power users. It is a key link to ensure that power is "available and available", and it is an important infrastructure for improving people's livelihood. Due to historical reasons, the distribution network is still one of the "two weak ends" in the development of the power grid. Compared with large power grids, distribution network planning and design, equipment level, construction standards, and reliability levels need to be further improved. There are still relatively lagging distribution network planning concepts and methods, uneven design levels and capabilities, and standardized There are outstanding problems such as low construction level. In order to c...
