Abstract

The EU-funded MARES project aims to develop a novel design of superconducting generator integrated into a wave energy converter (WEC). The superconducting generator consists of two parts, one assembled using REBCO tapes and the other using magnesium diboride (MgB₂) wires, with the latter offering a more cost-effective alternative. Assessing the optimal design of MgB₂ wires for this application is not straightforward, since AC losses represent a major technical issue of this device. In this work, a genetic algorithm is applied to determine the optimal design of the MgB₂ wires. The algorithm is coupled with a finite element method (FEM) electrodynamic model that computes the AC losses in the MgB₂ wires. The goal of the algorithm is to identify the key parameters of the wire configuration (filaments number and diameter, fill-factor, wire diameter, twist pitch) minimizing the AC losses in the device operating conditions.

低损耗MgB2导线的优化设计

欧盟资助的MARES项目旨在开发一种集成到波能转换器（WEC）中的超导发电机的新设计。超导发电机由两部分组成，一部分使用REBCO磁带组装，另一部分使用二硼化镁（MgB2）导线，后者提供了更具成本效益的替代方案。评估这种应用的MgB2导线的最佳设计并不简单，因为交流损耗是该设备的主要技术问题。在这项工作中，应用遗传算法来确定MgB2导线的最佳设计。该算法与计算MgB2导线交流损耗的有限元电动力学模型相结合。该算法的目标是确定导线配置的关键参数（灯丝数和直径、填充系数、导线直径、扭节距），使器件工作条件下的交流损耗最小化。
