摘要： The system and method described herein provide grid-forming control of a power generating asset having a double-fed generator connected to a power grid. Accordingly, a stator-frequency error is determined for the generator. The components of the stator frequency error are identified as a torsional component corresponding to a drivetrain torsional vibration frequency and a stator component. Based on the stator component, a power output requirement for the generator is determined. This power output requirement is combined with the damping power command to develop a consolidated power requirement for the generator. Based on the consolidated power requirement, at least one control command for the generator is determined and an operating state of the generator is altered.

摘要： A system for energy storage and electricity generation is described. The system includes an energy storage subsystem and an electricity generation subsystem coupled to the energy storage subsystem. The energy storage subsystem is configured to store energy in the form of compressed air at a temperature greater than a temperature of ambient air in the atmosphere. The electricity generation subsystem includes an airlift pumping system and a hydro-electric power system driven by the airlift pumping system, and is configured to produce electricity by utilizing the compressed air stored in the energy storage subsystem at the temperature greater than the temperature of ambient air in the atmosphere.

摘要： A generator, which may be used in a wind turbine, has a first stationary component carrying a first winding configuration and a second rotating component carrying a second winding configuration. The second rotating component includes a body portion and a plurality of teeth spaced around and extending radially from the body portion. The second winding configuration is arranged in slots defined between adjacent teeth. A housing is arranged around and rotates with the body portion. A heat exchange circuit is arranged on the second rotating component and includes a coolant channel defined in the teeth; a pump; and a heat exchanger arranged on the housing so as to rotate with the housing, the heat exchanger transverse to a rotational direction of the housing.

摘要： A buoyant hydrodynamic pump is disclosed that can float on a surface of a body of water over which waves tend to pass. The pump incorporates an open-bottomed tube with a constriction. The tube partially encloses a substantial volume of water with which the tube's constriction interacts, creating and/or amplifying oscillations therein in response to wave action. Wave-driven oscillations result in periodic upward ejections of portions of the water inside the tube that can be collected in a reservoir that is at least partially positioned above the mean water level of the body of water, or pressurized by compressed air or gas, or both. Water within such a reservoir may return to the body of water via a turbine, thereby generating electrical power (making the device a wave engine), or else the device's pumping action can be used for other purposes such as water circulation, propulsion, or cloud seeding.

摘要： Disclosed is air turbine charging system for electrically powered vehicle. The electrically powered vehicle includes air intake vents and air intake ducts that direct air inside the system with a specific force. The system further includes one or more air turbines coupled with one or more gears and one or more alternators. The air intake vents and air intake ducts direct air to cause rotation of an air turbine causing them and their coupled gears and alternators to rotate and cause an electric current. This electric current is used to charge the battery of the vehicle using a regulator that regulates power between alternator and battery. The amount of air intake from the air intake vents is varied automatically while the vehicle is on move based on predefined conditions. Moreover, there are two batteries associated with the system which are charged and are used alternatively for functioning of the vehicle.

摘要： A Sub-Terrestrial Updraft Tower (STUT), combination subsurface Downdraft/Updraft Tower, comprising an Inner Updraft Shaft and Outer Downdraft Shaft, housing the Inner Updraft Shaft, receiving air flow from air-inlets at surface level into Outer Downdraft Shaft. Upon reaching the bottom of the Outer Downdraft Shaft, air flow reverses In direction, inward and upward, into the Inner Updraft Shaft. Volumetric Displacement or airflow is induced and sustained via the injection of air and heat into the Downdraft/Updraft respectively; driving a plurality of sustained system pressure biases, and fed by temperature differentials that are initiated, sustained, and enhanced due to the configuration, orientations and functions of numerous STUT elements including partitions, thermal barrier coatings, air intake and cowlings; creating coherent, accelerated airflow to pass through/within a ringed shaped, diverging converging Vertical Axis Vertical Airflow Nozzle and Turbine (VAVANT); airflow causes rotation of VAVANT, and summation of torque forces at VAVANT hub, shaft, gearbox, and power head, generate EMF, and electrical power.
