Embodiment

[0057] According to the whole substation state evaluation system and evaluation method proposed by the present invention, the evaluation table of partial evaluation indicators of the substation is obtained.

[0058] The data analysis and processing process needs to be carried out in combination with the substation health index value table and the substation importance index value table. The important evaluation factors include setting the weight of the impact factor and matching the score of the impact factor according to the set conditions. The value of the influencing factor related to the health index of the substation is divided into 1 to 5 grades according to the health degree of the substation, in which 1 represents the best health degree and 5 represents the worst health degree. The substation health index value table is shown in Table 2 below:

Abstract

The invention discloses a system and method for evaluating the state of an entire transformer substation for equipment owners, and relates to the technical field of power system equipment state evaluation. The system herein includes a storage module, a detection module, a processing module and an evaluation module. The processing module carries out reasonable analysis and processing on respectiveevaluation index of the entire transformer substation so as to acquire the state of the entire transformer substation. The state provides a basis for determining the current state of the entire transformer substation in operation, enables in-time discovery of possible faults or defects in the entire transformer substation in operation and the follow-up maintenance and repair of the transformer substation, and can prevent power incidents. According to the invention, the method herein does not set the requirements for the weight sum to be 1, prevents the changes to the number of evaluation indexes in the computing from influencing the configuration of weights of existed evaluation indexes, and makes methods for evaluation more flexible.

Description

technical field [0001] The invention belongs to the technical field of power system equipment status evaluation, and in particular relates to an equipment owner-oriented substation whole substation status evaluation system and method. Background technique [0002] During the whole life cycle of a substation, the staff of different departments in the power grid have different concerns about the substation. The financial department mainly focuses on the purchase price, depreciation and maintenance costs of the substation, and the dispatching department mainly focuses on the operating data of the substation, such as voltage , current, load, etc. The operation and maintenance department pays attention to the operation status of the substation, such as defect conditions, test conditions, inspection conditions, etc. Each department sets up a corresponding index system according to different concerns, and evaluates the equipment, which unilaterally reflects a certain state of the s...
