摘要:

在这项工作中,我们提出了一个建模工具,旨在估计的磁滞损耗的线圈的发电机与线圈的涂层导体带在瞬态操作。该模型是基于一个两阶段的隔离模型的方法,允许模拟的发电机和电流分布的超导线圈使用的单向耦合从发电机的HTS线圈模型。该模型有两个输入:转速和电负载信号。线圈的均匀各向异性体模型允许计算线圈中的电流分布。从这个分布,滞后损失的估计。除了对机器中的全局能量耗散提供估计的兴趣之外,在这项工作中,我们提出了一个更详细的局部分析,该分析允许解决诸如线圈设计、临界电流额定、电负载变化率限制、制冷机设计、易失超区域的识别和整体瞬态性能等问题。

英文摘要:

In this work we present a modeling tool designed to estimate the hysteretic losses in the coils of an electric generator with coils made of coated conductor tapes during transient operation. The model is based on a two-stage segregated model approach that allows simulating the electric generator and the current distribution in the superconducting coils using a one-way coupling from the generator to the HTS coils model. The model has two inputs: the rotational speed and the electric load signal. A homogeneous anisotropic bulk model for the coils allows computing the current distribution in the coils. From this distribution, the hysteretic losses are estimated. Beyond the interest on providing an estimate on the global energy dissipation in the machine, in this work we present a more detailed local analysis that allows addressing issues such as coil design, critical current ratting, electric load change rate limits, cryocooler design, identification of quench-prone regions and overall transient performance.
