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

高压输电线路需要技术突破，以实现弹性和环境友好型城市电网，以及从可再生能源到负荷中心的长距离电力运输，这是一个不可否认的现实，需要解决。SUPERFEM响应了这一需求，提出了一套新的新型超材料，它将高温超导材料（HTS）的杰出电特性与软铁磁层（SFM）的屏蔽磁性结合在一起。我们将在高压直流和三相暖通电网的电源导体设计中引入这些材料，几乎为零磁漏和功率损耗。我们的HTS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，其中它们的优势已经在直流和单相网络中得到了探索。然而，电力行业的发电和终端使用几乎完全是交流的，对于这些，三相电力系统和直流网络将不得不共享通行权，其中影响高温超导网络运营成本的主要因素是其他每根电缆产生的磁场产生的损失。在您的博士学位期间，您将模拟高温超导单相和三相输电线路的实际电力应用，其中导体不仅仅是高温超导材料，从这个意义上讲，我们将研究用于改造地下输电线路的两种主要类型的绝缘方案，例如我们在英国的绝缘方案，但将增加高温超导/SFM元结构的新功能，以减少整个系统的滞后损耗。您将研究HTS/SFM暖导体的不同磁护套，以进入电源应用的SFM实际商业市场。您将致力于寻找节能和弹性输电网络，其长期目标是降低电网加固，更换和升级故障限制器和其他电源管理设备的成本，由于它们减少了在人口密集地区使用路权的需求，因此公众接受程度更高，安装成本更低。

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.
