Formation of Thermal Portraits of Electrical Devices Based on the Finite Element Method

Abstract

Here we consider the problem of obtaining thermal portraits for electrical devices of aviation power supply systems intended for use in intelligent power distribution systems in order to diagnose and predict the state of aviation electrical equipment. It is proposed to use a complete mathematical model in the form of heat conduction equations, implemented on the basis of the finite element method. The problem of forming thermal portraits of devices is being solved within the framework of expanding the functionality of promising intelligent digital power distribution systems. The use of such systems in aviation power supply systems is one of the important directions in the development of electric power complexes of aircraft.
