项目摘要

The collective efforts in aerospace, civil, electrical, and mechanical engineering areas have led to remarkable progresses in wind energy. Larger turbines are designed and installed, and wind farms are nowadays built at locations where wind is even more intermittent and maintenance equipment is less accessible. This adds new challenges to ensuring operational reliability. To cope with these challenges, along with the rapid advancement in microelectronics, modern wind farms are equipped with a large number and variety of sensors, including, at the turbine level, anemometers, tachometers, accelerometers, thermometers, strain sensors, and power meters, and at the farm level, anemometers, vanes, sonars, thermometers, humidity meters, pressure meters, among others. It is worth noting that all these data are currently analyzed/utilized only in their respective domains. The big data challenges in this project include how to best use spatio-temporal data for wind forecast, how to use data of different nature (wind, power, load etc.) and data of different sources (physical data versus computer simulation data) for power production assessment in a computationally efficient manner, and finally how to integrate these three sets of solutions into a reliable and efficient computational platform. The proposed research and education activities will make a paradigm shift in the wind industry by demonstrating how dramatically data science innovations can benefit the industry. The PIs will disseminate the research findings through classroom teaching, journal/conference publications, industry workshops, and data/software sharing. The summer internship opportunities and undergraduate research help train the next generation workforce to be better versed with data science methodologies.The critical barrier to cost effective wind power and its general adoption is partly rooted in wind stochasticity, severely complicating wind power production optimization and cost reduction. The long-term viability of wind energy hinges upon a good understanding of its production reliability, which is affected in turn by the predictability of wind and power productivity of wind turbines. Furthermore, the productivity of a wind turbine comprises two aspects: its ability of converting wind into power during its operation and the availability of wind turbines. Three inter-related research efforts will enhance wind energy reliability and productivity): (1) spatio-temporal analysis (for wind forecast) (2) conditional density estimation (for wind-to-power conversion assessment); and (3) importance sampling (for turbine reliability assessment and improvement). Significant data resourced provided by industry partners in the research, coupled with models and computational resources, will enable better prediction of wind profiles and utilization. In addition, the team will develop dedicated reconfigurable field programmable gate array (FPGA) processors that will be 50 to 500 times faster than general-purpose CPUs for both on-site and central control processing and have small form-factor, low cost and energy efficient to enable agile development under severe outdoor conditions at wind farms.

在航空航天、民用、电气和机械工程领域的共同努力下，风能取得了显著进展。更大的涡轮机被设计和安装，风力发电场现在建在风更间歇、维护设备更难获得的地方。这给确保运营可靠性增加了新的挑战。为了应对这些挑战，随着微电子技术的快速发展，现代风电场配备了大量和各种传感器，包括涡轮级的风速计、转速计、加速计、温度计、应变传感器和功率计，以及农场级的风速计、叶片、声纳、温度计、湿度计、压力计等。值得注意的是，所有这些数据目前仅在其各自的领域进行分析/利用。该项目中的大数据挑战包括如何最好地利用时空数据进行风预测，如何使用不同性质的数据(风、电力、负荷等)。和不同来源的数据(物理数据和计算机模拟数据)，以计算高效的方式进行电力生产评估，以及如何将这三套解决方案集成到一个可靠和高效的计算平台中。拟议的研究和教育活动将通过展示数据科学创新如何使该行业受益，从而使风能行业发生范式转变。投资促进机构将通过课堂教学、期刊/会议出版物、行业研讨会和数据/软件共享来传播研究成果。暑期实习机会和本科生研究有助于培训下一代劳动力，使其更好地精通数据科学方法。成本效益高的风电及其普遍采用的关键障碍部分源于风能的随机性，这严重影响了风电生产的优化和成本降低。风能的长期可行性取决于对其生产可靠性的充分了解，而可靠性又受到风能和风力涡轮机发电效率的可预测性的影响。此外，风力涡轮机的生产率包括两个方面：在其运行过程中将风转化为电能的能力和风力涡轮机的可用性。三个相互关联的研究工作将提高风能的可靠性和生产率)：(1)时空分析(用于风力预报)(2)条件密度估计(用于风电转换评估)；(3)重要性抽样(用于涡轮机可靠性评估和改进)。由行业合作伙伴在研究中提供的大量数据资源，再加上模型和计算资源，将能够更好地预测风廓线和利用率。此外，该团队将开发专用的可重构现场可编程门阵列(FPGA)处理器，在现场和中央控制处理方面将比通用CPU快50至500倍，并具有小巧的外形、低成本和高能效，使风电场能够在恶劣的室外条件下进行灵活开发。
