The Superconducting Magnetic Energy Storage (SMES) system is a modern and expensive technique for storage of electricity through the magnetic energy in superconducting short-circuited coil. An optimized configuration must reduce as much as possible the volume of the superconducting material. In this paper is proposed an optimized solution of modular toroid(More)
In this paper, an exhaustive optimization method based on design of experiments (DOE) and finite element method (FEM) was applied on a Superconducting Magnetic Energy Storage (SMES) device with modular toroid coil in order to optimize its storage capacity. Two geometric parameters defining the torus shape were chosen to maximize the stored magnetic energy(More)
The article presents the mathematical models and the results obtained has the numerical modelling of the thermal status of the electrical leads isolated for cryogenic applications. Model them mathematics are based on the equation of thermal conduction 1D and 2D. For the numerical resolution of the thermal conduction equation one uses the finite volumes(More)
