2.1. Land-based turbine control algorithms The pitch controller in above rated wind speed region is tuned by choosing the poles of the closed-loop one degree of freedom (DOF) drive-train model as suggested by Hansen et al. [21]. Assuming a rigid wind turbine structure, quasi-steady aerodyna...
Vertical-axis wind turbines are great candidates to enable wind power extraction in urban and off-shore applications. Currently, concerns around turbine efficiency and structural integrity limit their industrial deployment. Flow control can mitigate thes
To verify the algorithms experimentally, wind tunnel tests with a scaled wind turbine having active pitch control capability were performed. From the simulation and the test, the proposed DPPT algorithms integrated into the conventional control algorithm were found to work well with the basic wind ...
Both control algorithms, feedforward and fuzzy, operated satisfactorily. The tests showed that a Kalman filter must be used to give the fuzzy controller a good estimate of aerodynamic torque. Power output was controlled at all above-rated wind speeds. In the small turbine, maximum power was ...
A modified net present value calculation of the annual machine revenues and costs over the calculated life of the wind turbine is used to compare the merits of various control algorithms. Typical results are provided to demonstrate the use of the code. (ERA citation 12:040748) 著录项 作者 ...
The control system must be as optimized as possible, while meeting multiple (and sometimes conflicting) system requirements. Pitch and yaw controllers must also interact with supervisory logic controllers in order to operate and protect the turbine under a wide range of operating conditions. The ...
In this paper, a wind turbine mechanical load optimization control strategy based on an accurate wind speed estimator with time series Broad Learning System Method (BLSM) is designed, simulated and v...

and adapted to new grid conditions, through a series of complex calculations. This series of discontinuities in the control generate a response of the wind turbine in terms of the grid integration that may be improved and complex controller initialization algorithms are required for proper operation....
