The common goal of the research focus is the improvement of design and calculation methods for wind turbine load control solutions through experimental and numerical means. In addition to detailed high fidelity CFD simulations, engineering level design tools, which allow for parametric investigations or certification like simulations of different flow control concepts were developed during the first project phase. Additionally these tools are also used to project experimentally obtained results from wind tunnel tests to real size wind turbines. In PP1, a toolchain for the aero-elastic and unsteady simulation of flow control equipped wind turbine rotors has been established and validated. Successively the performance and feasibility of different flow control technologies considering realistic inflow conditions and aero elastic effects was investigated. However, many additional aspects of load control applications need further investigation before this technology can be integrated in the complex wind turbine system. To realistically asses the performance and potential of active and passive flow control, advanced simulations that not only include realistic unsteady aerodynamics, inflow and structural, but also realistic wind turbine controllers, shall be carried out. As wind turbines are often clustered in large windfarms, the effects of wake-rotor interactions on flow control performance, and the effect of flow control solutions on the loads and yield of successive turbines are questions that will also be addressed within the proposed prolongation. To achieve such feasibility for the simulation tools the functionality will be extended around the following aspects: In a first step the aerodynamic model will be extended with an advanced dynamic stall model, which also captures the dynamic lift response of flap movement. To enable the investigation of the interaction between flow control elements, their control and the resulting load changes with the main wind turbine controller, wind turbine controllers will be integrated in the simulation environment. Furthermore the code will be extended such that the mutual interaction between wind turbines in a wind park and the effects of this wake-turbine interaction on the feasibility and performance of different load control systems can be simulated. A focus during the continuation of development will be set on computational efficiency, as it is necessary to simulate a large amount of load cases to fully address the feasibility and performance of load control on wind turbine rotors.

研究的共同目标是通过实验和数值手段改进风力涡轮机负载控制解决方案的设计和计算方法。除了详细的高保真CFD模拟外，在第一个项目阶段还开发了工程级设计工具，这些工具允许进行参数调查或认证，如不同流量控制概念的模拟。此外，这些工具还用于将从风洞试验获得的实验结果投影到真实的尺寸的风力涡轮机。在PP 1中，已经建立并验证了用于装有流控的风力涡轮机转子的气动弹性和非定常模拟的工具链。随后，考虑实际来流条件和气动弹性效应，研究了不同流动控制技术的性能和可行性。然而，在将该技术集成到复杂的风力涡轮机系统中之前，需要进一步研究负载控制应用的许多其他方面。为了真实地评估主动和被动流量控制的性能和潜力，应进行高级模拟，不仅包括真实的非定常空气动力学、流入和结构，还包括真实的风力涡轮机控制器。由于风力涡轮机通常集中在大型风电场中，尾流-转子相互作用对流量控制性能的影响，以及流量控制解决方案对连续涡轮机的负载和产量的影响，也将在拟议的延长期内解决。为了实现这种可行性的仿真工具的功能将围绕以下几个方面进行扩展：在第一步，空气动力学模型将扩展为先进的动态失速模型，该模型还可以捕获襟翼运动的动态升力响应。为了能够研究流量控制元件之间的相互作用、它们的控制以及主风力涡轮机控制器导致的负载变化，风力涡轮机控制器将被集成到仿真环境中。此外，该代码将被扩展，使得风力发电场中的风力涡轮机之间的相互作用以及这种尾流-涡轮机相互作用对不同负载控制系统的可行性和性能的影响可以被模拟。在继续开发过程中，重点将放在计算效率上，因为有必要模拟大量的负载情况，以充分解决风力涡轮机转子负载控制的可行性和性能。
