Superconducting Ferromagnetic Metamaterials Enabling the Development of Resilient High Voltage / High Current Transmission Systems

需要在具有弹性和环境友好的城市电网的高压输电线路上取得技术突破，以及将电力从可再生能源远距离输送到负荷中心，这是一个需要解决的不可否认的现实。针对这一需求，SUPERFE提出了一种新型的超材料，它结合了高温超导材料(HTS)的出色电学特性和软铁磁层(SFM)的屏蔽磁性。我们将把这些材料引入到高压直流输电和三相交流输电网络的电力导体设计中，使其漏磁和功率损耗接近于零。我们的高温超导导体旨在为这些网络中的每一个提供无与伦比的性能特征，这些网络的好处已经在直流和单电流相网络中得到了探索。然而，用于发电和终端用途的电力工业几乎完全是交流的，对于这些，三相电力系统和直流网络将不得不共享通行权，其中，造成HTS网络运营成本的主要因素是由其他电缆产生的磁场产生的损耗。在您的博士学位期间，您将模拟HTS单相和三相电力传输线的实际电力应用，其中导体不仅仅是HTS材料，在这种意义上，用于改造地下电力传输线的两种主要类型的绝缘方案，例如我们在英国的那些，将被研究，但具有增加HTS/SFM亚结构以减少整个系统的滞后损失的新颖特征。您将研究用于HTS/SFM温导体的不同磁护套，并将其用于电力应用的SFMS的实际商业市场。你将致力于寻找高能效和有弹性的传输网络，长期目标是降低电网加固、故障限制器和其他电力管理设备的更换和升级成本，提高公众接受度并降低安装成本，因为它们减少了在人口稠密地区使用通行权的需要。

The need for a technological breakthrough in high voltage power transmission lines for resilient and environmentally friendly urban grids, as well as for the transport of power over long distances from renewable energy sources to load centers, is an undeniable reality that needs to be addressed. SUPERFEM responds to this need by proposing a new set of novel metamaterials which brings together the outstanding electric characteristics of High Temperature Superconducting materials (HTS) with, the shielding magnetic properties of Soft Ferromagnetic layers (SFM). We will introduce these materials in the design of power conductors for HVDC and three-phase HVAC networks, with nearly zero magnetic leakages and power losses. Our HTS conductors aim to offer unbeatable performance features for each one of these networks, where their benefits have been already explored for DC and single current-phase networks. However, the electric utility industry for generation and end usage are almost exclusively AC, and for these, three phase power systems and DC networks will have to share the right of way, where the major factor contributing to the operational costs of a HTS network, is the losses produced by the magnetic field created by each one of the other cables.During your PhD you will model real power applications of HTS single- and three-phase power transmission lines, where the conductor is more than just the HTS material, and in this sense two major types of insulation schemes for retrofitting underground power transmission lines, such as the ones we have in UK, will be studied but with the novel feature of adding HTS/SFM metastructures to reduce the hysteretic losses of the entire system. You will study different magnetic sheaths for HTS/SFM warm conductors into the actual commercial market of SFMs for power applications. You will be working on the search of energy-efficient and resilient transmission networks, which in the long term aims to mitigate costs of grid reinforcement, replacement and upgrade of fault limiters and other power management devices, with greater levels of public acceptance and lowering of installation costs, due their reduced need for use of the right of way in highly populated areas.
