基于REBCO带材的高温超导同步发电机转子线圈交流损耗计算方法及其影响因素
Calculation Method and Influence Factors of AC Loss of HTS Synchronous Generator Rotor Coil Based on REBCO Strip
摘要
Abstract
High-temperature superconducting(HTS)materials,with their zero-resistance properties,are ideal for use as excitation coils in the rotors of offshore wind turbine motors,enhancing power density and efficiency.However,since su-perconductors require cryogenic operation,the AC losses in HTS coils impact the cooling system design and overall machine efficiency.To address this issue,a novel method for calculating AC losses in HTS coils based on the T-A formu-lation is proposed,which divides the HTS coil into multiple regions to simplify the computational model and improve convergence.Validation results demonstrate that the proposed method achieves accurate calculations with significantly improved processing time.Through comparative studies of different motor structures,it is found that,when ferromagnetic stator teeth are employed,the iron-core rotor structure can reduce AC losses by over 70%compared to an air-core rotor.Further analysis reveals that the number of coil turns and the distance from the ferromagnetic teeth to the coil are two de-cisive factors influencing the losses.This research provides valuable insights for accurately calculating AC losses in rotor coils of HTS synchronous generators and,to some extent,offers guidance for the selection of superconducting motors and the design of superconducting coils.关键词
