  • Patent number: 11879425
    Abstract: A proactive method prevents vibrations in one or more rotor blades of a wind turbine when the wind turbine is in a standstill idling state with a rotor hub free to rotate. The method determines a minimum revolution rate of the rotor blades that prevents vibrations of the rotor blades and that the actual revolution rate of the rotor blades is below the minimum revolution rate. A wind parameter is detected and determined to be above a threshold limit. The method also detects if grid power is available for pitching the rotor blades. Based on the wind parameter, a controller determines a pitch angle for one or more of the rotor blades to increase rotation of the blades to at least the minimum revolution rate. The controller initiates pitching the rotor blades to increase the revolution rate of the rotor blades prior to vibrations being induced in the rotor blades.

    Abstract: The invention is directed at a substantially continuous unbroken frequency curve during operation modes from dump load operation, reverse power operation, low load operation and normal operation. Controlling functions are active during all operation modes except the engine controller which is on standby when in an engine stopped mode. This all together gives a dynamic, robust and flexible energy supply, preferably in a range of 50 to 50.3 Hz. Further the clutching is performed substantially without fluctuations. The invention substantially prevents harmonic fluctuations to the grid. The main reactive power compensation is handled by the alternator always connected to the grid and rotating. Further reactive power compensation is done by a standard automatic reactive power compensation system. The invention contributes to stabilization of grid fluctuations with its mechanical inertia from the rotating alternator in the engine stopped mode and also with the engine in the other modes.

The production system also includes a production control unit configured to control productivities of the first and second manufacturing machines. In response to detecting a breakdown sign in the first manufacturing machine, a stop time of the first manufacturing machine is predicted. After the detection of the breakdown sign and before the first manufacturing machine stops, the productivity control unit updates the productivities of the first and/or second manufacturing machines, causing the first manufacturing machine and/or the second manufacturing machine to have an updated productivity equal to or greater than its original productivity, such that a total productivity of the first manufacturing machine and the second manufacturing machine increases.

  • Patent number: 11770095
    Abstract: An apparatus for harvesting energy, such as solar, wind, wave, thermal, and the like, including a solar panel and a duct supporting the solar panel at an operational angle. The duct comprises a bottom shroud and side shrouds, therein forming a large aperture, a small aperture, and an oblique frustum shaped cavity. The oblique frustum shaped cavity is configured to direct a flow of fluid from the large aperture to the small aperture. A flow energy generator, such as a turbine, located at the small aperture is configured to collect flow energy. Temperature differences between the solar panel and the environment may be used to harvest thermal energy with a thermoelectric generator. Fluid flow under the solar panel may decrease the panel temperature and increase the efficiency. Generators may be operated in reverse to lower the solar panel temperature and increase efficiency.

  • Patent number: 11754039
    Abstract: The present application discloses novel systems and methods for yawing an autonomous wind turbine. In an embodiment, the wind turbine includes a control system configured to determine a control action signal for a yaw drive mechanism of the wind turbine as a function of the wind condition(s) and as a function of the load condition(s). The control system is configured to monitor change(s) associated with the load condition(s) to determine if the load condition(s) is too high for too long, or in need of attention, before yawing of the wind turbine is initiated or, if the load condition(s) are getting too high, after yawing has been initiated. In another embodiment, the control system includes a load sensor system with proximity sensors arranged adjacent, on, and/or about the main shaft flange of the nacelle or on the rotor blades of the wind turbine.

  • Patent number: 11746748
    Abstract: A method of operating a wind energy installation wherein a rotor has a first rotor blade which can be angularly adjusted, a first adjustment drive for adjusting the rotor blade, and a safety control system. In a normal mode of operation, the first adjustment drive is supplied with energy from a source and is controlled by a first pitch control system. In a failure mode of operation, the supply of energy to the first adjustment drive is switched from the source to an energy storage device and the safety control system monitors a position and/or movement of the first rotor blade. The first rotor blade is adjusted by the first adjustment drive in a direction of a predetermined stopping position, while the safety control system, as a function of the monitored position and/or movement, enables or effects a deactivation of a first power supply shut-off device.
