Holistic Subsea Cable Fault Detection & Condition Monitoring System

海上风力发电比陆上风力发电面临更恶劣的环境，这可能对关键基础设施的可靠性带来更大的挑战。对海上风电场经济成功至关重要的一项资产是海底电缆基础设施。这包括阵列内和出口电缆，其故障将导致无法出口发电而导致收入的重大损失，以及监管机构的处罚。自2013年以来，由于海底电缆故障，海上产生的8 TWh电力已经损失，导致运营商损失10亿英镑。在海上风电行业，保险索赔总成本的80%归因于电缆故障，而海底电缆支出仅占新风电场资本成本的9%。因此，需要更好的电缆或增强的故障检测和监控系统，以减少可检测到的电缆故障的数量，并在故障情况下最大限度地减少损失的发电量。目前，没有一个现有的系统能够在检测到故障时准确识别、定位并提供缓解措施。SmartCable将为海底电缆状态监测带来一个彻底的解决方案，Proserv集成了众多最先进的监测系统及其生成的数据，首次为运营商提供：海底电缆健康的全貌，用于预测性维护，节省成本，减少故障，这将首次使电缆监测系统能够部署在新的和现有的海上电缆上。风力发电场由Proserv开发的SmartCable系统将作为一个决策支持平台，从海底电缆光纤和主芯中获取大量数据-温度，机电，局部放电和声学数据-并将其集中关联，开发新的通用数据语言并应用定制的机器学习算法，为所有者运营商提供有关电缆状况的可操作智能，并且在故障发生之前很久就在尽可能早的阶段检测到操作故障。这将使电缆故障的有效预测，允许采取应急措施，以减少故障的风险和维修计划。在Levenmouth演示涡轮机（LDT）的演示过程中的性能指标和系统数据的分析将允许系统的长期鲁棒性和稳定性在海上环境中得到验证，并在商业化之前进行优化。

Power generation from offshore wind is subject to harsher environments than onshore wind, which can cause greater challenges for the reliability of critical infrastructure. One asset that is fundamental to the economic success of an offshore wind farm is the subsea cable infrastructure. This includes intra-array and export cables, failure of which will lead to significant loss of revenues through failure to export generated power, as well as penalties imposed by regulators. Since 2013, 8 TWh of electricity generated offshore has been lost due to subsea cable faults resulting in £\>1bn of losses for operators. In the offshore wind industry, 80% of the total cost of insurance claims are attributed to cable failures, while subsea cable expenditure only accounts for 9% of the capital cost of a new windfarm. Therefore, better cables or enhanced failure prognostics and monitoring systems are required to reduce the number of detectable cable failures and minimise the lost generation in the event of a fault. At present, no existing system is capable of accurately identifying, locating and offering mitigation in the event that a fault is detected.SmartCable will bring a radical solution to subsea cable condition monitoring, with Proserv integrating numerous state-of-the-art monitoring systems and the data they generate to provide operators with, for the first time, a complete picture of subsea cable heath for predictive maintenance with cost savings associated with reduced failures, and optimised repair scheduling.This will enable for the first time a cable monitoring system that can be deployed on subsea cabling for new and existing offshore wind farms. The SmartCable system, to be developed by Proserv will act as a decision-enabling platform to take the wealth of data -- temperature, electro-mechanical, partial discharge and acoustic data from the subsea cable fibre optic and main cores -- and correlate it centrally, developing a new common data language and applying bespoke machine learning algorithms to provide actionable intelligence to owner-operators on cable condition, and detect an operational fault at the earliest possible stage, long before a failure will take place. This will enable effective prediction of cable failure, allowing for contingency actions to be taken to reduce the risk of failure and plan for repairs.Analysis of the performance metrics and system data during a demonstration at Levenmouth Demonstration Turbine(LDT)will allow the long-term robustness and stability of the system to be validated in an offshore environment and optimised prior to commercialisation.
