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发展至关重要，尤其是海上风力发电，目前风力发电占英国总发电量的7.7%。通过状态监测系统进行预防性维护，可以提高风电场的可靠性和可用性，降低维护成本，从而降低“平准化能源成本”（LCOE）。绿色解决方案工程有限公司开发了SmartCMS，这是一种独特的状态监测技术，利用转换器中可用的电气测量来检测和诊断风力涡轮机传动系统（即齿轮箱，轴承，发电机和转换器）的机械和电气故障。该项目已在实验室测试台上进行了成功测试，旨在通过在试点风力涡轮机传动系统上进行测试，评估其技术和商业可行性，并研究净降低LCOE的经济性，从而将SmartCMS带入下一阶段的开发。

Reliability is vital in the growth of wind power, especially offshore installations, currently generating 7.7% 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 in a pilot wind turbine drivetrain and study of the economics with respect to net reduction in the LCOE.
