Implementing the wind speed estimation algorithm in the target embedded control system
To improve power production, wind turbine control system use information regarding the wind speed. Unfortunately, wind speed can’t be enough accurately measured and measurement is not a good representative of the rotor effective wind speed. Therefore, wind speed estimation is necessary. This paper describes an algorithm for the estimation of the effective wind speed, based on the aerodynamic torque. It is assumed that the rotor speed and generator torque are measured. Wind speed enters into the generator dynamics through a highly nonlinear function, so there is a difficult problem of estimation of a nonlinearly parameterized system. To solve this problem secant method proved to be suitable. The algorithm is implemented in a conventional wind turbine control system, in the processor module, which contains a 32-bit microcontroller. The algorithm is implemented in fixed-point arithmetic using 16 bits with sign and has been validated by comparison with the Matlab simulation results. The benefit of this estimation algorithm is reflected in the anemometer fault detection. Therefore, the system availability is increased up to 0.5-1%.
