Embodiment Construction

[0021] The method and system for site selection and capacity determination of the low-voltage line voltage regulator of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] refer to figure 1 , figure 1 Shown is a flow chart of a method for site selection and capacity determination of a low-voltage line voltage regulator in an embodiment, including the following steps:

[0023] S10, identifying the low-voltage demarcation point and the distribution transformer of the target distribution network, and obtaining the demarcation point distance between the low-voltage demarcation point and the distribution transformer;

[0024] The above-mentioned low-voltage line may be a 380V (volt) low-voltage line. The target distribution network is the distribution network in remote areas such as rural areas. The possible problems of the above-mentioned target distribution network include: the grid is unstable, the grid structure is r...

Abstract

The invention relates to a site selection constant-volume method and system for a w-voltage line voltage regulator. The method comprises: a low-voltage demarcation point and a distribution transformer of a target distribution network are identified to obtain a demarcation point distance between the low-voltage demarcation point and the distribution transformer; a line load type of the target distribution network is identified and a load increasing promotion coefficient of the target distribution network is set according to the line load type; on the basis of the demarcation point distance and the load increasing promotion coefficient, a mounting point distance of a low-voltage line voltage regulator is determined, and a mounting site of the low-voltage line voltage regulator is selected at a circumference by using the distribution transformer as a center of circle and the mounting point distance as a radius; and load nodes beyond the circumference by using the distribution transformer as the center of circle and the mounting point distance as the radius are identified to obtain a first selected load node, a total load capacity corresponding to the first selected load node is obtained, and a configuration capacity of the low-voltage line voltage regulator is determined based on the total load capacity and the load increasing promotion coefficient.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method and system for site selection and capacity determination of a low-voltage line voltage regulator. Background technique [0002] With the rapid improvement of the economic level, various power systems have been popularized in various regions. In relatively remote areas such as rural areas, the economy has also grown rapidly, and electricity consumption is also rising. During the construction of the power system, more construction funds are invested in the power supply and backbone grid, and insufficient attention is paid to the construction of power grids in remote areas such as rural power grids, thus causing the development of distribution networks in these remote areas to lag behind. The characteristics of the distribution network in these remote areas include many points, wide area, long lines, low load rate, strong seasonality and insufficient reactive power...
