摘要
本文介绍了环境湍流对潮汐风电场的影响。首先,使用Bahaj和Myers(2004)开发的分析模型,并对其进行修改,以纳入环境湍流效应。通过Mycek et al.(2014)的实验考虑了环境湍流,其中测试了两个水平的湍流,即3%和15%。对尾迹速度缺陷的修正进行了处理。然而,考虑了通常被忽略的环境湍流对下游涡轮功率系数的影响。对于较低水平的湍流,考虑了下游涡轮行为的三种情况。这个增强的模型然后在奥尔德尼竞赛(Raz Blanchard)的给定地点进行测试。根据环境湍流、涡轮机布局和建议方案,评估和比较每年的能源产量。并进行了技术经济分析。最后,潮汐风电场的盈利能力在很大程度上取决于环境湍流和涡轮机布局。
Semi-analytical estimate of energy production from a tidal turbine farm with the account of ambient turbulence
This paper presents the influence that ambient turbulence has on a tidal turbine farm. Firstly, the analytical model developed by Bahaj and Myers (2004) is used and modified in order to incorporate the ambient turbulence effects. Ambient turbulence is taken into account via the experiments of Mycek et al. (2014), where two levels of turbulences were tested, namely 3% and 15%. Modifications in wake velocity deficit are treated. However, the influence that ambient turbulence has on the power coefficient of downstream turbine(s), which is usually neglected, is taken into account. For the lower level of turbulence, three scenarios for the downstream turbine(s) behaviour are considered.
This enhanced model is then tested on a given site in the Alderney Race (Raz Blanchard). Yearly energy productions depending on ambient turbulence, turbine layouts and proposed scenarios are evaluated and compared. A technico-economical analysis is also carried out. Finally, the tidal turbine farm profitability highly depends on ambient turbulence and turbines layout.
