Dynamic torque balancing mechanism in counter-rotating dual-rotor wind turbines

The invention is a blade control and torque balancing mechanism (100) developed for use in dual-rotor wind turbines, characterized by a generator (101) with a rotor and stator connected to two separate shafts, allowing them to rotate in opposite directions. The generator (101) includes two covers and an outer shell with bearing housings and circlip slots. It also features a servomotor (105) linked to a lead screw (108) to adjust angles based on active torque measurement and a decision mechanism; a lead screw (108) that moves forward and backward through the servomotor (105); a torque meter (106) connected to the shafts exiting from the generator (101) rotor and stator to measure the torque generated by the front and rear turbine blades (114); a connection arm (110) that moves along the lead screw (108), allowing the shaft (117) to rotate with the turbine blades (114); an elliptical triangular connection apparatus (111) with bearing and circlip holes for mounting the shaft (117) and servomotor (105), designed to rotate synchronously with the turbine blades (114) and to adjust blade angles by moving with the connection arm (110) back and forth; and a blade connection apparatus (118) positioned on the shaft (117) to adjusting the desired angle actively changing the angle of the turbine blades (114).

Yaw control using average motor speed reference as feedback

This invention relates to a method for controlling the yaw of a wind turbine system by controlling multiple yaw drive actuators. Based on a requested motor speed reference as an input signal and an average motor speed reference as a feedback signal, the method determines a desired motor torque reference as the output signal for the multiple yaw drive actuators. The multiple yaw drive actuators rotate the nacelle or a structure comprising multiple nacelles, thereby providing a uniform load distribution to the multiple yaw drive actuators.

Control yaw to reduce motor speed

This invention relates to a method for controlling the yaw of a wind turbine system by controlling multiple yaw drive actuators. When the yaw drive actuators apply the same torque to all motors, if the motors are not engaged when the yaw system is activated, this can cause some motors to overspeed. Therefore, if the actual motor speed reference of a yaw drive actuator is higher than a specific motor speed reference, an output signal is applied to the yaw drive actuator whose actual motor speed reference is higher than the specific motor speed reference to reduce the actual motor speed reference.

Method for controlling a wind turbine farm using an optimization method

ActiveFR3147598B1Optimise machine performanceWind motor controlAir velocityLoad model
The present invention relates to a method for controlling a wind farm that implements a data acquisition (QAC) of a wind speed and direction distribution, as well as a real-time wind speed and direction acquisition (Vac), a wind farm model (MOD F), and a load model (MODC) for each wind turbine. Subsequently, an optimization step (OPT) determines target operating points for each wind turbine. This optimization step optimizes the expected energy generated for the entire wind speed and direction distribution as a function of the expected load for each wind turbine across the same distribution. These target operating points (e.g., target yaw angles) are then applied to the wind turbines in the farm (CON). Figure 2 to be published
