Abstract

This work presents results from a new field-testing campaign conducted on the three-bladed Controls Advanced Research Turbine (CART3) at the National Renewable Energy Laboratory in 2014. Tests were conducted using a commercially available, nacelle-mounted continuous-wave lidar system from ZephIR Lidar for the implementation of a lidar-based collective pitch feed-forward controller. During the campaign, the data processing of the lidar system was optimized for higher availability. Furthermore, the optimal scan distance was investigated for the CART3 by means of a spectra-based analytical model and found to match the lidar's capabilities well. Throughout the campaign the predicted correlation between the lidar measurements and the turbine's reaction was confirmed from the measured data. Additionally, the baseline feedback controller's gains were tuned based on a simulation study that included the lidar system to achieve further load reductions. This led to some promising first results, which are presented at the end of this paper.

CART3上CW-lidar系统前馈控制器的优化

这项工作展示了2014年在国家可再生能源实验室对三叶片控制高级研究涡轮机(CART3)进行的一项新的现场测试活动的结果。为了实现基于激光雷达的集体俯仰前馈控制器，测试人员使用了ZephIR激光雷达公司的一个商用的、安装在机舱内的连续波激光雷达系统。在战役期间，激光雷达系统的数据处理进行了优化，以提高可用性。此外，通过基于光谱的分析模型对CART3的最佳扫描距离进行了研究，并发现与激光雷达的能力相匹配。在整个活动中，激光雷达测量和涡轮机反应之间的预测相关性从测量数据中得到了证实。此外，基线反馈控制器的增益根据包括激光雷达系统在内的模拟研究进行了调整，以进一步降低负载。这导致了一些有希望的初步结果，这些结果在本文的最后提出。
