Patent number: 11879425Abstract: 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.Type: GrantFiled: December 8, 2021Date of Patent: January 23, 2024Assignee: GE Infrastructure Technology LLCInventor: Darren John Danielsen

Patent number: 11878444Abstract: A method for producing a hollow composite structure, such as a spar beam for use in a wind turbine blade, includes placing fiber reinforcement material around a mandrel within a mold, and curing the fiber reinforcement material. The mandrel is formed from a compressible material having a rigid neutral state with a rigidity to maintain a defined shape of the mandrel during lay up and curing of the fiber reinforcement material. Subsequent to curing, a vacuum is drawn on the mandrel to compress the compressible material so that the compressed mandrel can be drawn out through an opening in the composite structure, the opening having a size such that the mandrel could not be withdrawn through the opening in the rigid neutral state of the mandrel.Type: GrantFiled: December 11, 2018Date of Patent: January 23, 2024Assignee: GE Infrastructure Technology LLCInventors: Louis Rondeau, Aaron A.

Patent number: 11876375Abstract: A power grid restoration system includes a hybrid power plant that provides electrical power to a power grid. The hybrid power plant includes a power plant that generates electrical power with a power drive. A battery energy storage system, which receives and stores electrical power from the power plant, releases the electrical power during block loading of the power grid. A controller couples to the power plant and to the battery energy storage system. The controller controls charging of the battery energy storage system with the power plant and controls the release of a block load of electrical power from the battery energy storage system and the power plant while block loading the power grid during a black grid restoration.Type: GrantFiled: August 21, 2019Date of Patent: January 16, 2024Assignee: GE INFRASTRUCTURE TECHNOLOGY LLCInventors: Robert Samuel Rodick, Mazdak Haeri Foomani

Publication number: 20230358179Abstract: A dispatch advisor for operating a power plant having at least one gas turbine with flexibility is described. The dispatch advisor can generate a representation of a flexible base load map for operating the power plant. The representation can include an aggregation of a primary base load operating space and an expanded portion of the base load operating space. The representation offers a range of operating values for operational parameters of the power plant during base load at various base load settings at predetermined ambient conditions and corresponding power output and efficiency values that are attained while operating the power plant at the range of operating values. This offers an operator of the power plant with flexibility in controlling the plant during base load.Type: ApplicationFiled: July 18, 2023Publication date: November 9, 2023Applicant: GE INFRASTRUCTURE TECHNOLOGY LLCInventors: ILYA ALEXANDROVICH SLOBODYANSKIY, DAVID LEACH, BERARDINO PEZZELLA

Patent number: 10844837Abstract: An apparatus and system for compensating for various load situations in a turbine includes the use of one or more deployable devices configured to extend an air deflector outwardly from a surface of a rotor blade. The air deflector may subsequently be retracted into the rotor blade once the load falls below a certain threshold. Mechanisms for extending and retracting the air deflector may include pneumatic, hydraulic and/or electromechanical devices. Air deflectors are generally configured to modify the air flow around the rotor blade to increase or decrease power generation, or reduce loads so that the risk of potential damage to components of the wind turbine is minimized. Deflectors may be positioned at various chordwise stations including leading-edge, mid-chord, and trailing-edge locations on the upper and lower surfaces at spanwise positions. Accordingly, a plurality of devices can be actuated to aerodynamically control rotor performance and loads based on wind conditions.Type: GrantFiled: June 5, 2012Date of Patent: November 24, 2020Assignee: GE Infrastructure Technology, LLCInventors: Jonathon P.
