Embodiment
[0093] see figure 1 The schematic diagram of the system scheme is shown. The SCADA system can monitor various data during the operation of the wind turbine and save them in low-frequency data mode. The embodiment of the present invention is based on the generator torque T in the SCADA datag The wind rotor speed w is the state quantity, the wind speed v and the pitch angle β are the input quantities, and the generator power p is the measurement quantity. During the operation of the wind turbine, the generator torque T can be obtained by reading the existing data of the SCADA system g and the optimal state estimation value and covariance of the wind rotor speed w at time k-1 to construct the sigma point and the corresponding weight. After the SCADA system finishes sampling and saving the data of the wind turbine at time k, it reads the wind speed and pitch angle at time k as the input of the Unscented Kalman method, and then according to the wind turbine system equation f(x(k) ...
