Abstract:
Abstract Clustering multiple turbines in close vicinity gives rise to efficiency losses due to the energy extraction of upstream turbines, a phenomenon known as the wake effect. The risk wake-induced power losses pose for the economic feasibility of wind farm projects motivated several methodologies aimed at mitigating the wake effect by dynamically exciting one operational parameter of the upstream turbine. Among them are dynamic yawing, which sinusoidally varies the yaw angle of the turbine with the wind, and helix active wake control, which dynamically manipulates the turbine thrust. This s

Abstract. This article presents the results of an experimental wind tunnel study which investigates a new control strategy named Helix. The Helix control employs individual pitch control for sinusoidally varying yaw and tilt moments to induce an additional rotational component in the wake, aiming to enhance wake mixing. The experiments are conducted in a closed-loop wind tunnel under low-turbulence conditions to emphasize wake effects. Highly sensorized model wind turbines with control capabilities similar to full-scale machines are employed in a two-turbine setup to assess wake recovery poten

Abstract This paper investigates the effectiveness of the Helix control strategy for a 3 × 3 wind farm in neutral atmospheric boundary layer flow using large eddy simulations of IEA 15MW wind turbines in terms of power production and blade and tower loadings. Various control scenarios are considered, with a maximum power gain of 7% obtained in the case where the first two columns of the wind farm are controlled with the Helix controller. It is shown that the power gain strongly depends on the phase difference of the first and second-column wind turbines’ Helix signal. However, we show that the

Abstract:
Abstract Power losses at waked turbines due to the energy extraction of upstream turbines from the flow pose a major risk to the economic feasibility of wind farms. Helix active wake control has proven its potential to mitigate these wake-induced power losses by accelerating the recovery of the individual turbine wakes. This method leverages individual pitch control to induce a non-uniformly distributed force perturbation that rotates either in a clockwise (CW) or counterclockwise (CCW) direction around the rotor center. This deforms the wake into a helical shape that recovers faster than the

Abstract:
Abstract A promising method to reduce wake effects in offshore wind farms is the Helix approach, which increases the mixing of the wake with the surrounding flow by exciting the individual blade pitch. This increases the wind speed in the wake, resulting in a higher power output at a downstream turbine. Wind tunnel testing is crucial to gather further understanding of the governing mechanisms behind the Helix and its efficiency in larger wind farm arrays. However, model turbines are expensive and complex. Porous Discs (PD) have proven to supply a less expensive and less complex alternative for

In the present wind energy research, Darrieus-type vertical-axis wind turbines are increasingly appreciated, especially in small installations. In particular, H-shaped turbines can provide attractive spaces for novel design solutions, aimed at reducing the visual impact of the rotors and then at improving their degree of integration with several installation contexts (e.g. a built environment); moreover, novel small rotors are thought to be able in the near future to make large use also of new and cheaper materials (e.g. plastic or light alloys) which could notably reduce the final cost of the

After almost 20 years of absence from research agendas, interest in the vertical axis wind turbine (VAWT) technology is presently increasing again, after the research stalled in the mid 90’s in favour of horizontal axis turbines (HAWTs). However, due to the lack of research in past years, there are a significantly lower number of design and certification tools available, many of which are underdeveloped if compared to the corresponding tools for HAWTs. To partially fulfil this gap, a structural FEA model, based on the Open Source multi-physics library PROJECT::CHRONO, was recently integrated w

Two of the main challenges for the design of offshore wind turbine foundations are the need for silent installation techniques and for large tensile capacity.
