摘要： A modular rotor blade for a power generating turbine allows simple replacement of individual rotor blade sections in case of damage to or malfunction of a section. The modular rotor blade includes at least two rotor blade sections, wherein each rotor blade section includes at least one connecting part having at least one conical opening. The connecting parts of adjacent rotor blade sections rest against each other such that the conical openings of the connecting parts are aligned with each other and form a continuous conical connecting opening. Receiving elements for receiving tensioning elements are arranged at the smaller diameter end of the conical connecting opening. A conical bolt corresponding to the continuous conical connecting opening is arranged therein, and at least one tensioning element passes through the conical bolt and tensions the conical bolt against the receiving element.

摘要： A wind powered turbine with low voltage ride-through capability. An inverter is connected to the output of a turbine generator. The generator output is conditioned by the inverter resulting in an output voltage and current at a frequency and phase angle appropriate for transmission to a three-phase utility grid. A frequency and phase angle sensor is connected to the utility grid operative during a fault on the grid. A control system is connected to the sensor and to the inverter. The control system output is a current command signal enabling the inverter to put out a current waveform, which is of the same phase and frequency as detected by the sensor. The control system synthesizes current waveform templates for all three-phases based on a sensed voltage on one phase and transmits currents to all three-phases of the electrical system based on the synthesized current waveforms.

摘要： A turbine control system for a variable speed electrical generator in a wind turbine mounted atop a support tower. The wind turbine converts wind energy into a driving torque applied to the generator. The control system includes a turbine support tower position sensor and may also include other tower acceleration and velocity sensors. A wind flow estimator uses the measured motion, generator rotation rate and blade pitch angle to predict wind flow over the swept area of the turbine's rotor, and the tower motion. The predicted wind flow and motion is used in the turbine control system to properly adjust its operating point, to tune the controller, to control the rotor rotation rate, and to damp tower oscillations.

摘要： A variable speed wind turbine employing a rotor connected to a multiplicity of synchronous generators with wound field or permanent magnet rotors. A passive rectifier and an inverter are used for power transfer back to the grid. A Turbine Control Unit (TCU) commands a required generator torque based on rotor speed and power output of the turbine inverters. Torque is controlled by regulating the DC current by control of the inverter. A main-shaft-damping filter is provided by measurement of the DC bus voltage. In high winds the turbine remains at a constant average output power through a constant torque command and a varying pitch command to a rotor pitch servo system. A set point is fixed at the inverter output such that output VAR load is minimized running the turbine at very nearly unity power factor. Dynamic VAR and power factor control is provided by a separate VAR apparatus.

摘要： A controller for high torque, low RPM wind turbines and ocean current turbines. The turbine consists of a large, input power shaft-mounted, rotating bull-gear with stationary powertrains mounted around its periphery. The gear teeth on the bull-gear rotate past the teeth on pinions, causing the pinions to turn and delivering power to each smaller powertrain. A controller regulates torque experienced by each powertrain to assure that torques are balanced between generators at any given system load. The control method comprises the programmatically continuously looping steps of measuring a system parameter to be controlled, such as torque and/or speed, selecting the optimal number of generators to be connected/disconnected to a utility line, incrementally connecting or disconnecting generators to achieve the point of optimal performance, measuring the parameters, such as current and/or voltage, of the connected generators and adjusting the generator parameters to fine tune the system for optimal performance.
