Embodiment

[0053] Example: Carry out secondary equipment differential transformation for a 220kV substation in Jiangsu. First, according to the actual problems and needs of the substation, the elements contained in the target problem of hierarchical analysis are selected, and the elements with dominant logical relationship are summarized and hierarchical, and then a hierarchical model for the evaluation of differentiated transformation schemes is constructed. Then, set up a three-person evaluation expert group, from the substation owner, secondary equipment manufacturer and design institute respectively, and the expert empowerment is 0.4, 0.3, 0.3 respectively. Finally, follow the steps described to evaluate the retrofit proposal. In order to simplify the expression, only the calculation process of the weight vector among the factors of the criterion layer is given, and the evaluation and weight determination steps of the elements of the criterion layer are the same for the second-level ...

Abstract

The invention discloses a method for selecting a differentiated transformation scheme for secondary equipment of electric power. A hierarchical analysis structure including a scheme layer, a criterion layer and a target layer is constructed according to the use history information of secondary equipment and related norms and standards, and then the above-mentioned For the calculation model and quantification method of each index, the triangular intuitionistic fuzzy number theory is used to fuzzify all the indexes; the fuzzy analytic hierarchy process is improved by defining a new scoring function, and the weight of each index is calculated based on the fuzzy number algorithm, and then stratified Sort. The present invention is based on the triangular intuitionistic fuzzy theory to select the differentiated transformation scheme of the secondary power equipment. Compared with other linear evaluation and sorting methods, it solves the problems of unclear definition fuzziness and incompleteness of statistical information in the evaluation process, and at the same time retains effective information, reduce the influence of subjective factors, and improve the ability of substations to carry out accurate secondary equipment differentiation technical transformation.

Description

technical field [0001] The invention belongs to the field of power grid technical transformation evaluation, and in particular relates to a method for selecting a differentiated transformation scheme for secondary electric power equipment. Background technique [0002] Smart grid is the focus of current power system development, and the number of supporting smart substations continues to increase. With the transformation and upgrading of substations, a large number of substations are approaching or exceeding life expectancy and need to be renovated. In addition to the wearing parts and power modules that can be replaced regularly according to the maintenance plan, the traditional mainstream secondary equipment operation and maintenance and transformation are all carried out according to the plan and the passive "one-size-fits-all" solution for troubleshooting, that is, by replacing the screen cabinet (including the inside of the cabinet) device and terminal block) and the e...
