Problems solved by technology

[0003] Transformers are subjected to normal load and overload at the same time in actual operation. Existing transformer life simulation estimation methods usually only consider the effect of normal load, and do not specifically involve research on overload, so the accuracy of life assessment is not high.

Embodiment Construction

[0043] Embodiments of the present invention are described in detail below, examples of which are shown, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.

[0044] Although the operator generally does not allow the transformer to suffer severe overload or long-term overload from the perspective of safe system operation, adding overload considerations in the life simulation of the transformer has a great impact on the accuracy and evaluation of the life of the transformer. The overload capacity of the transformer is of great significance. For this reason, the present invention proposes a kind of transformer life simulation estimation method considering overload situation, can comprise the following steps:

[0045] (1) Obtain the...

Abstract

The invention discloses a transformer life simulation estimation method, and relates to the technical field of electrical equipment. On the basis of the linear cumulative damage theory, the general simulation estimation method of a transformer life model under the combined action of a normal load and an overload is put forward. The method provides the possibility for calculating more load impacts, can be matched better with transformer life according to actual statistics and is higher in applicability. Based on the simulation estimation method, the transformer life can be accurately estimated, and the deep research such as prediction of the transformer life and estimation of the overload capacity of a transformer can be achieved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a transformer life simulation estimation method. Background technique [0002] As the key hub equipment in the power system, the power transformer plays a vital role in ensuring its reliable operation for the safe and stable operation of the power system. The time that the transformer can run for a long time under load is called the life of the transformer. [0003] Transformers are subjected to normal load and overload at the same time in actual operation. Existing transformer life simulation estimation methods usually only consider the effect of normal load and do not specifically involve research on overload, so the accuracy of life assessment is not high. Contents of the invention [0004] The purpose of the present invention is to propose a transformer life simulation estimation method based on linear cumulative damage theory, to overcome the shortcomings of ...
