Key Technologies for High- Field Superconducting Magnets in Fusion Reactors
High-field superconducting magnet technology is critical for improving the operational performance of large scientific devices like magnetic confinement fusion systems. The stable operation of these magnets under extreme electromagnetic stress cycles and rapid excitation conditions faces significant technical challenges, such as suppressing critical characteristic decay, rapidly calculating loss heat deposition and accurately evaluating stability margins. This presentation addresses these issues by proposing stress-strain relationships and calibration models that relate spatial irradiation to superconducting magnet critical characteristics. It also discusses the development of high-precision, multi-scale AC loss calculation models and introduces a stability calculation framework for the “critical state effect-AC loss heat deposition”. These advancements provide a foundation for optimizing the performance and safety of large fusion high-field superconducting magnets, with applications extending to superconducting energy storage, magnetic levitation, and superconducting motors.

This Flux-modulation electric machines have been gaining interest over the last few decades, which exhibit the advantage of high-toque density due to the flux-modulation effect. Typically, conventional flux-modulation electric machines have one electrical port (stator windings) and one mechanical port (rotor/shaft). An integrated flux-modulation electric machine with two electrical ports and two mechanical ports would be introduced in this speech, i.e., this machine consists of two sets of stator windings and two rotors. Moreover, this integrated flux-modulation electric machine is featured with the “dual flux-modulation” effect, which helps to improve the torque density. The topology, operating principles, and electromagnetic characteristics of this dual flux-modulation electric machine would be presented in detail. Furthermore, the performance metrics of this integrated machine used for the two-degree-of-freedom applications would be presented, including variable-speed constant-frequency wind turbines, contra-rotation wind turbines, hybrid electric vehicles, etc.

Abstract
The insulation problems in special environments, such as multiple lightning strikes, icing, heavy pollution, and heavy salt spray, are becoming increasingly prominent. Using lightning protection composite insulators as an example, we explore the external insulation discharge mechanism， the establishment of discharge models under special circumstances, and the insulation state sensing technology. Firstly, a physical model for the critical development of AC arc in lightning protection composite insulators and an AC flashover model were proposed to address the unsuitability of traditional insulator flashover models for composite insulators. Secondly, a dynamic pollution flashover model is constructed as the theoretical basis for insulation control, and collaborative optimization algorithms are used to explore the control strategies for the insulation structure of composite insulators. Finally, the latest external insulation state sensing technology was explored through practical applications such as heavy pollution flashover warnings and intelligent insulator zero measurements.
