基于温度场计算的油浸式变压器热点温度仿真分析方法
Simulation analysis method of hot spot temperature of oil-immersed transformer based on temperature field calculation
摘要
Abstract
With the construction of large-capacity pumped storage power plants,the problem of transformer winding overheating become more prominent.Given the technical shortage of the real-time monitoring for hot spot tempera-ture of oil-immersed transformers in pumped storage power plants,taking a large oil-immersed transformer as the re-search object,and the finite element and heat transfer principle are taken as theoretical basis,a hot spot tempera-ture simulation analysis method based on temperature field distribution calculation is proposed in this paper.A magneto-thermal coupling finite element simulation is carried out.The winding structure and oil flow conditions are simplified,and the simulation parameters are set based on existing technical parameters and monitoring data.The temperature field distribution results meeting engineering requirements are calculated,so that the hot spot tempera-ture is obtained.The rationality and accuracy of the temperature field distribution calculation are verified by compa-ring the monitoring data,the standard model calculation results and the simulation results of the top oil temperature and hot spot temperature of transformer.The proposed simulation analysis method provides a new solution for hot spot temperature detection in pumped storage power plants.关键词
