Renewable Energy Array Cable and Termination Instrumentation using Optical sensor Networks (REACTION)

“海上风力发电比陆上风力发电面临更恶劣的环境，对关键基础设施的可靠性提出了更大的挑战。特别值得关注的是海底输出和阵列内电缆，其故障可能导致发电和维修成本的重大损失。据报道，在海上风电场，此类故障占保险索赔总成本的75-80%，而总布线支出仅占新风电场资本成本的9%左右。需要显著增强的保护和监控系统来确保这些关键资产的鲁棒性，并在发生故障时最大限度地减少损失的发电量，但现有的仪表解决方案无法以低成本提供实施此类系统所需的可见性。该项目将提供所需的创新解决方案，该解决方案基于由英国SME Synaptec Ltd开发的独特光子传感器技术，首次实现了海上系统的成本有效的分布式电气仪表。该技术将使强大的差动保护方案能够部署在阵列电缆上，以便在发生电缆故障时立即识别受影响的部分，从而大大减少相关的发电停机时间和收入损失。使用该技术所利用的丰富信息可进一步用于谐波测量，谐波测量可用于识别已知会削弱绝缘的电缆谐振条件。结合在已知故障点上的兼容光纤温度测量以检测热点，这将首次实现在集成平台上预测电缆故障，从而可以采取快速应急措施以降低故障风险或提前计划维修，从而通过有针对性的维护延长使用寿命。ORE Catapult将提供工程和市场专业知识，并使Synaptec能够在位于法夫郡Levenmouth的OREC 7 MW测试涡轮机上的真实环境中测试本项目中开发的海底电缆监测/保护平台。在试验期间记录测量和系统数据将首次评估安装在海上环境中的Synaptec传感器的长期稳定性。Synaptec和OREC将检查这些丰富的数据，以确定除了基本的故障电缆检测功能之外还可以获得哪些辅助信息，例如基于谐波信息的电能质量测量和故障诊断。OREC将利用其在海上可再生能源领域的专业知识和联系，提出商业案例，并组织利益相关者研讨会，以确保该项目开发的技术准确满足行业需求。"

"Offshore wind power generation is subject to harsher environments than onshore wind, imposing greater challenges on the reliability of critical infrastructure. Of particular concern are subsea export and intra-array cables, failure of which can lead to significant loss of generation and repair costs. In offshore wind farms, such failures are reported to account for 75-80% of the total cost of insurance claims, while total cabling expenditure accounts for only around 9% of the capital cost of a new windfarm. Significantly enhanced protection and monitoring systems are required to ensure robustness of these key assets and minimise lost generation in the event of a fault, but no existing instrumentation solution provides the required visibility at low cost to implement such a system.This project will deliver the required innovative solution, built around unique photonic sensor technology developed by UK SME Synaptec Ltd, enabling for the first time cost-effective distributed electrical instrumentation of offshore systems. The technology will enable robust differential protection schemes to be deployed on array cabling for immediate identification of the affected section in the event of a cable fault, significantly reducing associated generation downtime and loss-of-revenue. The wealth of information leveraged using this technology can further be used for harmonic measurements, which can be used to identify cable resonance conditions known to weaken insulation. Combined with compatible fibre-optic temperature measurement on known points of failure to detect hotspots, this would enable for the first time prediction of cable failure on an integrated platform, allowing swift contingency actions to be taken to reduce the risk of failure or plan ahead for repairs, enabling lifetime extension through targeted maintenance.ORE Catapult will contribute engineering and market expertise, and enable Synaptec to test the subsea cable monitoring/protection platform developed in this project in a realistic environment on OREC's 7MW test turbine in Levenmouth, Fife. Logging of measurement and system data during the trial will allow the long-term stability of Synaptec's sensors installed in offshore environments to be assessed for the first time. Synaptec and OREC will examine this wealth of data to determine what ancillary information can be obtained beyond basic faulted cable detection functionality, e.g. power quality measurements and failure prognostics based on harmonic information. OREC will leverage its expertise in and contacts throughout the offshore renewables sector to produce a commercial case and organise stakeholder workshops to ensure the technology developed by this project accurately addresses the industry need."
