有限元和有限体积法结合的油浸式变压器温度场计算方法
The calculation method of temperature field of oil immersed transformer with FEM and FVM combined
摘要
Abstract
Oil immersed transformer is an important equipment of power system.In order to accurately calculate the temperature field of oil immersed transformers, a hybrid method which is based on comparison of respective advantages of the finite element method ( FEM) and finite volume method ( FVM) is proposed in this paper.It takes a transform-er of 110 kV/31.5 MVA as example, using mixed method of finite element method and finite volume method, the three-dimensional temperature field of transformer is calculated.By comparing the data of top oil temperature of trans-former monitored by the operating transformer and the solution calculated by mixed method, the margin error of the hot spot temperature is only 1.6 ℃, which proves that this hybrid method can accurately calculate the internal tempera-ture field of oil immersed transformer.关键词
