A Deep Learning Approach to the Transformer Life Prediction Considering Diverse Aging Factors

Abstract: The reliability of a high-capacity power transformer is fundamental to the stable operation of power systems. However, characterization of the transformer aging process is a difficult task, considering the diverse aging factors in its life cycle. This prevents effective management of such equipment. In the work, we study the aging phenomenon of power system transformers, whose representative degeneration variables are extracted from real transformer operational data. Combining with the average life of the equi… Show more

“…As a key component of the power system, power equipment will not only affect the power equipment itself, but also have an immeasurable impact on the large power grid system when serious faults occur (He et al, 2022). Therefore, the reliability of power equipment in smart substations must receive due attention, particularly in increasingly complex power systems.…”

“…У створеній моделі є чотири вихідних MF (рис. 4 г): Деградацію ізоляції котушок можна оцінити за допомогою індексу деградації (LoL), який використовується в теплових моделях реального трансформатора [22][23][24]. Вважається, що підвищення температури 𝛥𝜃 𝑂.𝑡 і 𝛥𝜃 𝐻𝑆𝑂.𝑡 не залежать від температури охолоджувального середовища в діапазоні її зміни від +40 до -20 °C [24].…”
