Embodiment 10

[0051] The evaluation steps of the 10kV distribution network low-voltage control scheme in this embodiment are as follows:

[0052] Step 1. Establish a low-voltage governance evaluation system in terms of governance effects, economic benefits, and development adaptability, such as image 3 , 4 , 5 shown.

[0053] Step 2. Set weights for each indicator of the evaluation system:

[0054] The auxiliary matrix is ​​determined by constructing the "auxiliary judgment matrix" and "auxiliary summation matrix", and the index weight is obtained by combining the eigenvector method.

[0055] Auxiliary judgment matrix, as shown in formula (1):

[0056]

[0057] Among them, the auxiliary judgment matrix W is a square matrix of n×n, n>2, and its diagonal is 0, satisfying w ij =1 / w ji , i≠j, i,j=1,2,3,...n,w ij is the i-th element a i The value of the auxiliary judgment matrix W is determined according to formula (2) according to the ratio of the relative importance of the jth eleme...

Abstract

The invention provides a 10kV power distribution network low voltage automatic management planning and assessment method. The 10kV power distribution network low voltage automatic management planning and assessment method includes a one-key type automatic planning for 10kV power distribution network low voltage management, multiple-step type guiding planning of 10kV power distribution network low voltage management, and comprehensive assessment of a 10kV power distribution network low voltage management scheme. The 10kV power distribution network low voltage automatic management planning and assessment method is a set of low voltage management process, and can realize the one-key type automatic management planning scheme through software. The 10kV power distribution network low voltage automatic management planning and assessment method also designs the guiding type multiple-step planning, selects one of three management measures through guiding of software: exchanging of wires, reactive compensation and configuration of a voltage regulator, only performs single step of management for each selection, and can perform automatic planning on the basis of single step reconstruction. The comprehensive assessment method of 10kV power distribution network low voltage management designs a three dimensional assessment system, can obtain the index weight by reconstructing an auxiliary judgment matrix and an auxiliary sum matrix, and finally can realize the calculating process of assessment.

Description

technical field [0001] The invention relates to a low-voltage automatic planning management and evaluation method of a 10kV distribution network, belonging to the technical field of power grid planning. Background technique [0002] The low voltage problem of the 10KV distribution line is manifested in the phenomenon that the voltage of the end node of the line is lower than 7% of the nominal voltage, that is, when the voltage at the end of the line is lower than 9.3KV, it is called the low voltage of the 10KV distribution network. Due to the diversification of the 10KV distribution line structure, the reasons for the low voltage of the distribution network are also different, so a specific treatment plan is required for targeted treatment. The traditional low-voltage control process of distribution network can be summarized as the following four steps: (1) Analyze the low-voltage status of 10kV distribution network through historical operation data and field investigation; ...
