The invention provides an active
yaw control method for a single-point
mooring floating type draught fan platform, and belongs to the technical field of
offshore wind power. A
wind direction angle is obtained in real time through a
wind direction sensor, and the deviation between the
wind direction angle and the
azimuth angle of a platform main shaft is judged; the
system calculates the average wind direction in a set time window so as to suppress the influence of high-frequency wind direction disturbance. The controller dynamically calls a
model predictive control (MPC)
algorithm according to wind direction deviation, outputs a target rotation angle of the flow guide
rudder, drives the flow guide
rudder to adjust the direction of the flow guide
rudder, generates a
yaw moment acting on the platform, and guides the platform to rotate around a single-point
mooring rotor to realize active wind facing; the guide rudder
assembly and the hydraulic driving
system are arranged between the vertical columns with the heaving plates in cooperation with the platform, accurate and rapid
attitude control can be achieved, and the wind facing capacity and the
structural stability of the draught fan are remarkably improved. According to the wind
turbine platform, the wind facing posture can be adjusted in real time according to the change of the wind direction, so that the wind energy utilization efficiency is improved, and the power generation requirement under the deep and far sea complex environment is met.
