Abstract
In order to ensure the safe and reliable operation of the transformer, a method for estimating the healthy operation state of the 110kV power grid transformer based on key characteristic quantities is proposed. The key characteristic quantities of 110kV power grid transformer operation are analyzed. According to the analysis results, from the perspective of harmonic loss, transformer insulation and oil and gas analysis, a method for estimating the healthy operation state of 110kV power grid transformers is designed. The experimental results show that the estimation results of the method in this paper are consistent with the actual operating conditions, and the estimation results have a high accuracy rate, indicating that the research results of this method are more reliable.
