Abstract

In the pursuit of optimizing superconducting generator systems, a comprehensive understanding of their electro-thermal behaviors is crucial. This study builds upon previous research on an 8-pole, 10 MW superconducting generator by Inanir et al. (2022, Journal of Superconductivity and Novel Magnetism, 35(11), 3189) and focuses on an in-depth electro-thermal analysis of the rotor coil system. The emphasis is on assessing the AC losses experienced during transitory current changes. By simultaneously solving Ampere's equation and the heat conduction equation under specific boundary conditions, the research provides a detailed insight into the interaction between electrical and thermal dynamics within the rotor coils. The paper highlights the importance of temperature dynamics in various cooling and current conditions. The results demonstrate that achieving an optimal balance in cooling, particularly with the use of liquid nitrogen, is critical for efficient operation. This study not only advances the understanding of superconducting generators but also highlights potential strategies for improving their reliability and efficiency.

超导发电机的电热动力学：深入研究 10 兆瓦转子线圈系统的交流损耗和冷却技术

为了优化超导发电机系统，全面了解其电热行为至关重要。本研究以 Inanir 等人之前对 8 极 10 兆瓦超导发电机的研究（2022 年，《超导与新型磁学杂志》，35（11），3189）为基础，重点对转子线圈系统进行了深入的电热分析。重点是评估过渡电流变化期间的交流损耗。通过同时求解安培方程和特定边界条件下的热传导方程，该研究提供了对转子线圈内电动态和热动态之间相互作用的详细见解。论文强调了各种冷却和电流条件下温度动态的重要性。结果表明，实现冷却的最佳平衡，特别是使用液氮，对于高效运行至关重要。这项研究不仅加深了人们对超导发电机的了解，还强调了提高其可靠性和效率的潜在策略。

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
