摘要
本研究提供了一项风洞调查,以确定降低上游涡轮机功率的有效方法,从而减少尾流引起的功率损失。短程连续波激光雷达测量用于远程绘制可控模型风力涡轮机在均匀流入和可忽略湍流条件下的时间平均尾流特征。分析重点是比较四种不同的静态感应控制(SIC)策略与传统的贪婪策略,每种策略的目标降额水平分别为 5% 和 10%。结果表明,在双涡轮设置中,变桨-变羽结合增加顶速比是最大限度减少尾流损失的最有利方法。值得注意的是,在降额 5%、涡轮间距较小的情况下,部分和全部尾流重叠条件下的功率增益可达 3.8%。这些观察结果与之前的现场实验一致,表明 SIC 在风机间距较近的风电场中可能具有优势。总之,这些发现强调了谨慎选择和理解所实施的降额策略对于支持风电场流量控制应用的重要性。
On the impact of different static induction control strategies on a wind turbine wake
This study provides a wind tunnel investigation to identify effective ways of derating an upstream turbine for mitigating wake-induced power losses. Short-range continuous-wave lidar measurements are used to remotely map the time-averaged wake characteristics of a controllable model wind turbine under uniform inflow with negligible turbulence. The analysis focuses on comparing four distinct static induction control (SIC) strategies, each at targeted derating levels of 5 % and 10 %, against a conventional greedy strategy. The results indicate that pitch-to-feather combined with an increased tip-speed ratio is the most favourable approach for minimising wake losses in a two-turbine setup. Notably, power gains of up to 3.8 % are achieved for partial and full wake overlap conditions at 5 % derating and small turbine spacing. These observations are consistent with previous field experiments, suggesting that SIC may be advantageous in wind farms with closely spaced turbines. Overall, these findings underscore the importance of carefully selecting and understanding the implemented derating strategy for supporting wind farm flow control applications.
