Embodiment Construction
[0053] refer to figure 1 , which is a flow chart of an embodiment of the electromechanical coordination suppression method for vibration of the rotating main shaft of a vertical axis wind turbine according to the present invention. This embodiment comprises the following steps:
[0054] S100, start.
[0055] S110. Obtain the vertical inclination of the rotating main shaft in real time.
[0056] The vertical inclination angle includes the inclination angle value α in the two orthogonal directions in the horizontal section of the main axis x and alpha y . The inclination angle value can be obtained by installing a two-axis inclination sensor on the stationary part at the top of the rotating spindle.
[0057] S120. Calculating the vibration intensity K of the rotating main shaft v .
[0058] The tremor intensity is defined as, K v = α x 2 ...
