Reducing the ‘levelised cost of energy’ in offshore wind through a disruptive fault diagnosis technology, SmartCMS

可靠性对风力发电的增长至关重要，特别是海上设施，目前风力发电约占英国发电量的8%。通过状态监测系统实现的预防性维护提高了风电场的可靠性和可用性，并降低了维护成本，从而降低了“统一能源成本”(LCOE)。格林解决方案工程有限公司开发了SmartCMS，这是一项独特的状态监测技术，利用变速器中可用的电气测量来检测和诊断风力涡轮机传动系统(即变速箱、轴承、发电机和变速器)中的机械和电气故障。在实验室试验台上成功测试后，该项目旨在将SmartCMS带入下一阶段的开发，通过在试点风力传动系统上进行测试来评估其技术和商业可行性，并研究LCOE净减少的经济性。

Reliability is vital in the growth of wind power, especially offshore installations, currently generating ~8% of UK electricity. Preventive maintenance, enabled by condition monitoring systems, increases reliability and availability of wind farms as well as reducing maintenance costs, leading to a lower 'Levelised Cost of Energy' (LCOE). Green Solution Engineering Ltd has developed SmartCMS, a unique condition monitoring technology which utilises the electrical measurements available in the converter to detect and diagnose both mechanical and electrical faults in the wind turbine drivetrain (i.e. gearbox, bearings, generator and converter). Having been successfully tested on a laboratory test bench, this project aims to take SmartCMS to the next phase of exploitation through assessment of its technical and commercial feasibility through testing on a pilot wind drivetrain and study of the economics with respect to net reduction in the LCOE.
