Systems, methods, and non-transitory computer readable media including instructions for coordinated braking of a plurality of geographically-associated fluid turbines. Coordinated braking of a plurality of geographically-associated fluid turbines includes accessing memory storing information indicative of a tolerance threshold for an operating parameter associated with the plurality of geographically-associated fluid turbines; receiving information from a sensor indicative of the operating parameter for a particular fluid turbine among the plurality of geographically-associated fluid turbines; comparing the information indicative of the operating parameter for the particular fluid turbine with the tolerance threshold; determining, based on the comparison, whether the operating parameter for the particular fluid turbine deviates from the tolerance threshold; and upon a determination that the operating parameter for the particular fluid turbine deviates from the tolerance threshold, sending a braking signal to each of the geographically-associated fluid turbines to slow each of the geographically-associated fluid turbines.

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).

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.

This disclosure describes many innovations including but not limited to systems, methods, and non-transitory computer readable media containing instructions for coordinated braking of a plurality of geographically-associated fluid turbines. Coordinated braking of a plurality of geographically-associated fluid turbines includes accessing memory storing information indicative of a tolerance threshold for an operating parameter associated with the geographically-associated fluid turbines; receiving information from at least one sensor indicative of the operating parameter for a particular fluid turbine among the plurality of geographically-associated fluid turbines; comparing the information indicative of the operating parameter for the particular fluid turbine with the tolerance threshold; determining, based on the comparison, whether the operating parameter for the particular fluid turbine deviates from the tolerance threshold; and upon a deviation from the tolerance threshold, sending a braking signal to each of the geographically-associated fluid turbines to slow each of the geographically-associated fluid turbines.

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.

Control of a multi-rotor wind turbine system. A local controller is arranged for each wind turbine module and implementing a local model predictive control (MPC) routine. A central controller is arranged to determine a set of operational constraints of the wind turbine modules. Based on a current operational state of the wind turbine module and the set of operational constraints, one or more predicted operational trajectories are calculated and used for controlling the wind turbine module.

The present disclosure relates to a system for arranging a set of turbines in a fluid flow in a channel, the system (200) comprising at least one turbine arrangement (100) and a control unit (210). Each turbine arrangement (100) comprises a turbine arrangement body (110), at least one turbine (120), and turbine moving means (130). The system (200) comprises at least two separate turbines (120). Each turbine (120) is attached to the corresponding turbine arrangement body (110), and is arranged to separately be moved to a plurality of positions (112) by the turbine moving means (130). Each turbine (120) is arranged to be in said fluid flow and arranged to harvest energy from fluid flow (160). The control unit (210) comprises a computer (211) arranged to receive, for each turbine (120), turbine data comprising values indicative of the amount of harvested energy by said turbine and its position (112); determine a target position (112) for each turbine (120) based on said received turbine data; and control turbine moving means (130) to arrange the turbines (120) based on the corresponding determined target positions (112).

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
