During the energy exchange process with the grid, the losses of superconducting magnetic energy storage (SMES) magnets are unavoidable and will cause temperature rise, which may lead to serious consequences such as quench. In recent years, many literatures have studied the AC losses and thermal characteristics of SMES under specific operating conditions, but there has been little research into the factors that influence AC losses and temperature rise. In this paper, a reduced dimensional finite element simulation model based on T-A equation is established to investigate the influence of different response speed, energy and initial temperature of the magnet on the AC loss and temperature rise of a 3 MJ magnet, which provides a theoretical basis for the optimization of SMES control and state evaluation.
