For the UK to meet legally binding renewable targets by year 2020 and beyond, a series of wind farms are under construction, and more new projects are being developed. The offshore grids and their connection to the existing transmission systems can only be realised using the HVDC links. Using high voltage will make power transmission more efficient and the only feasible solution is to use extreme upgrades to existing plant. Cables, the key part of the HVDC links, will be forced to operate well beyond their existing limits (currently about +/-500 kV and 1000 MW). This means that both cable insulation and operating conditions have to be pushed far beyond the limits currently considered acceptable. Therefore, a fundamental understanding of the performance of the insulation and the development of novel operating methodologies are urgently required to meet the challenges. This project will investigate the impact of inherent defects, space charge dynamics, partial discharges, electrical tree and power quality on electrical performance of highly stressed lapped cable insulation and develop novel operating methodologies that take account of the influence of the above factors to achieve reliable and safe operation for the HVDC links.

为了使英国在2020年及以后达到具有法律约束力的可再生能源目标，正在建设一系列风电场，并正在开发更多的新项目。仅使用HVDC链接才能实现离岸网格及其与现有传输系统的连接。使用高压将使电力传输更加高效，唯一可行的解​​决方案是对现有工厂进行极端升级。电缆是HVDC链接的关键部分，将被迫远远超出其现有限制（目前约为+/- 500 kV和1000兆瓦）。这意味着电缆绝缘和操作条件都必须远远超出当前被认为可以接受的限制。因此，迫切需要对绝缘性能和新型操作方法的发展的基本理解以应对挑战。该项目将研究固有的缺陷，空间电荷动态，部分放电，电气树和功率质量对高应力的拉动电缆绝缘材料的电性能的影响，并开发出新颖的操作方法，这些方法可以考虑上述因素的影响，以实现HVDC链接的可靠和安全操作。
