specific Embodiment

[0063] In order to facilitate the understanding of the solution of the present invention, a specific example is used for description below, but this specific example does not constitute a limitation to the present invention.

[0064] In this specific embodiment, a power grid that needs to build a new 110kV substation is used as an example to perform simulation calculations. image 3 shows the topology of the grid, image 3 ◎ in it is 220kV substation; ○ is 110kV substation; the number in brackets is the capacity of a single transformer, and the unit is MVA; is the candidate site; 1, 2, and 3 next to the candidate site are the candidate site numbers.

[0065] (1) by image 3 It can be seen that the total number of addressing schemes n=3, such as image 3 As shown, the addressing schemes are numbered from 1 to 3, and the counting variable k=1 is set;

[0066] (2) Collect the main transformer capacity S of the 110kV substation of the k-th location scheme k , load rate T k ...

Abstract

A method and system for site selection of a 110kV substation, the method comprising the steps of: separately obtaining the main transformer capacity, load rate, total capacity of the installed distribution transformers, interval utilization ratio, 10KV line overload rate, 10KV line non-transferable rate, 10KV line trunk overlength rate; respectively determine the correlation degree of each 110kV substation according to the main transformer capacity and the distribution transformer total capacity; Index standardization; combining the 10KV line overload rate, 10KV line non-transfer rate, 10KV line trunk overlength rate, and the load rate, correlation degree, and interval utilization rate after standardization of indicators, determine the coordination of the site selection plan corresponding to each 110kV substation degree; select the site corresponding to the site selection scheme with the highest degree of coordination as the final site, which can improve the coordination of medium-voltage distribution network operation while ensuring the reliability of the distribution network.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a site selection method and system for a 110kV substation. Background technique [0002] The location and capacity of the 110kV substation play a decisive role in the coordination of high and medium voltage distribution networks such as power supply capacity, power supply balance, and reliability. For example, the site selection of a 110kV substation has a great influence on the length and difficulty of the 10kV outgoing line. However, considering the impact of topography, environmental protection, municipal planning, etc., sometimes the construction site of the 110kV substation given by the government department during the site selection process of the 110kV substation is remote, resulting in a certain distance between the 110kV substation and the load center, and the power supply radius is too large, which in turn affects The impact of line loss and voltage drop is mor...
