Calculation of AC loss using 2D homogenization method for HTS synchronous condenser rotor and validation
Compared with low-temperature superconductors, second-generation high-temperature superconducting materials offer higher current densities and temperature margins, which provide a boost to the development of superconducting condenser towards large capacity and light weight. In this paper, a 3D-to-2D dimensionality reduction and simplification method is proposed to address the problem of massive computation of 3D finite element model during the optimization of superconducting condenser rotor performance parameters. This method splits the pole based on the geometric characteristics of the rotor pole, establishes a 2D simplified model of each part of the pole after splitting, and uses the simplified model to calculate the key physical quantities such as the magnetic field, AC loss, temperature change, etc., during the excitation process of the superconducting condenser rotor. This method effectively reduces the computational complexity of the model and improves the efficiency of the calculation and iterative optimization of the magnet pole parameters. In order to verify the correctness of the electromagnetic calculation results of the simplified model, the rotor magnet model was assembled to carry out experiments in liquid nitrogen bath, and the experimental results were in good agreement with the calculation results.
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.
