Assessing Consequences of Wind Turbine Active Power Control

该项目旨在为加拿大领先的风能试验场提供所需的分析工具，以探索风电场运营的新战略。加拿大风能研究所(Wecan)拥有并运营一个10兆瓦的风力发电场，用于电力生产和研究。人们对有源功率控制的研究兴趣与日俱增，在有源功率控制中，涡轮机功率输出不断调整，以满足当地电力系统波动的需求。如果可以调整风电场的发电量，以帮助匹配需求或其他发电的每一分钟的变化，那么风电场实际上可以帮助电网的稳定。然而，改变AWIND涡轮机的运行会带来额外的结构负荷和增加损耗的风险，最终会缩短风电场的寿命或增加运营成本。探索有功功率控制需要更好地理解潜在的后果。对于像威康这样的研究机构来说更是如此，它有兴趣试验新的和创新的控制策略。为了解决这个问题，UPEI团队将开发Wecan风力涡轮机的模拟模型。这些模型将与威嘉公司合作，根据现有涡轮机的测量结果进行调整，然后经历威肯公司有兴趣进行试验的不同场景。通过分析风力机力和偏差方面的仿真结果，我们可以估计各种运行策略和各种环境条件下对风力机健康的影响。最终，这些结果以及用于生产这些结果的新开发模型将使威肯深入了解其涡轮机可以安全地探索哪些有功功率控制场景，从而使未来能够探索和演示新颖的风力涡轮机运营策略。

This project aims to provide Canada's leading wind energy test site with the analysis tools needed to explorenew strategies for wind farm operation. The Wind Energy Institute of Canada (WEICan) owns and operates a10 MW wind farm for power production and research purposes. A growing research interest is in active powercontrol, where turbine power output is adjusted on an ongoing basis to meet the fluctuating needs of the localelectricity system. If wind farm output can be adjusted to help match minute-by-minute changes in demand orother generation, then wind farms can actually assist with stability of the power grid. However, changing awind turbine's operation runs the risk of introducing additional structural loads and increasing wear and tear,ultimately reducing wind farm lifetime or increasing operating costs. Exploring active power control thereforerequires a better understanding of the potential consequences. This is all the more true for a research institutionsuch as WEICan, which has interest in experimenting with new and innovative control strategies. To addressthis, the UPEI team will develop simulation models of WEICan's wind turbines. These models will be tuned incollaboration with WEICan based on measurements of the existing turbines, and then put through differentscenarios that WEICan has interest in experimenting with. By analysing the simulation results in terms of windturbines forces and deflections, we can estimate the consequences on wind turbine health from variousoperating strategies and under a range of environmental conditions. Ultimately, these results, and the newlydeveloped models used to produce them, will give WEICan insight into what active power control scenarios itcan safely explore with its turbines, enabling future exploration and demonstration of novel wind turbineoperating strategies.
