Abstract

The invention discloses a power transformer state evaluation method and device. The method comprises the following steps: detecting each to-be-detected part based on the evaluation parameter of each to-be-detected part of a power transformer to obtain a detection result; according to the detection result, performing quality evaluation on the to-be-detected part to obtain an evaluation grade of each evaluation parameter of the to-be-detected part; determining a parameter score Gi, a normalization weight Wi and an emphasis weight We, i corresponding to the evaluation parameter; and obtaining a rating score of the to-be-detected equipment according to the parameter score Gi, the normalized weight Wi and the weighted weight We, i. According to the invention, more comprehensive information can be provided for operation and maintenance personnel, so that auxiliary decision making can be carried out when the power transformer equipment is diagnosed.

Description

technical field [0001] The invention relates to the technical field of grid equipment safety, in particular to a method and device for evaluating the state of a power transformer. Background technique [0002] As a key component of the power grid, the power transformer plays a vital role in the transmission and distribution of electric energy. Its reliability is an important guarantee for the safe and stable operation of the power system. Therefore, it is extremely important to determine the operating status of power transformers. It is the premise of discovering equipment problems and intervening in time. It is of great significance to reduce the failure rate of transformer insulation, prolong the service life of equipment, and improve the reliability of power grid systems. [0003] At present, with the promotion and development of unattended substations, higher requirements are put forward for the operation and maintenance management level of substation equipment, especial...
