2000 w wind turbine output power adjustment method

Oct 09, 2018

In the 2000 w wind turbine, the power output is qualitatively divided into two categories according to the different power supply modes. One is to adjust the mechanical power, and the wind turbine control loop plus adjusting device makes the wind turbine output mechanical power stable; Adjust the electric power, add feedback to the control part of the generator, use the fast response controller and optimize the control strategy to control the generator output power.


When the wind speed is higher than the rated wind speed, the angle of attack of the airflow increases to the stall condition, causing eddy currents on the surface of the 2000 w wind turbine blade to reduce the aerodynamic efficiency of the blade and affect energy capture. Small wind power system maximum power control disturbance method Stall speed regulation is generally used in wind turbines with constant speed operation.


In order to improve the wind energy conversion efficiency and ensure the smooth output of the wind turbine, the 2000 w wind turbine can be adapted to the wind speed change by the pitch adjustment to achieve the optimal power output. When the rated wind speed is above, the pitching mechanism works to adjust the blade angle of attack to ensure that the power of the generator is within the allowable range.


Another mode of adjustment for the 2000 w wind turbine is active stall regulation, which is a combination of the first two power adjustment methods. At low wind speeds, variable pitch adjustment can be used to achieve higher aerodynamic efficiency; when the fan reaches the rated power, the fan changes the pitch in the opposite direction of the pitch when the fan is adjusted according to the pitch adjustment. This adjustment will cause the blade. The change in the angle of attack results in a deeper stall and smoother power output.https://www.titanwindturbine.com/
