15 paź 2020 · An appropriate yaw angle misalignment of the wind turbines in a wind farm has been found to improve the average energy production of the turbine array. Predicting the spatial evolution of the yawed turbine wakes is a key factor in optimizing the yaw angles.
22 gru 2014 · The goal of the work presented here is to optimize the yaw angles of the wind turbines for increased total electrical power production of the wind plant. By changing the yaw angle of a turbine, the flow direction of the wake, as well as the axial induction of the rotor, is changed.
It is time to monitor the yaw system of your wind turbines. The wind vanes, the yaw controller and the yaw drive are in charge of aligning the turbine with the wind. By minimising the angle between the wind and the turbine, the power output is maximized and non-symmetrical loads are avoided.
7 sty 2013 · BlueScout Technologies has shown, on a variety of turbines, that power increases can be achieved when improved wind angle information is fed into the yaw control systems of turbines. However, this early work typically uses the legacy control strategy of the turbine.
18 gru 2023 · We demonstrate the utility of the dynamic yaw model in two examples of model-based control of the power output of a wind farm. These applications confirm that the dynamic yaw model accurately predicts the transient response of the wind farm to yaw actions and within an active yaw control loop.
1 gru 2023 · The model can be used to quickly obtain the wake flow distributions of yawed wind turbines, and optimize the yaw control scheme of each wind turbine by changing its yaw angle, so as to redirect the wake flow to obtain the maximum output energy of the wind farm.
Currently, almost all wind turbines use pitch control systems and yaw systems. The yaw drives control the alignment of the nacelle with the wind; the pitch control system is constantly adjusting the angle of attack of the rotor blades—the pitch angle—in order to achieve the greatest possible energy yield.
