A wind turbine generator, or other energy extraction device, has a hydraulic circuit comprising a hydraulic pump driven by a rotating shaft and a hydraulic motor driving an electricity generator. When the electricity generator is switched off, it executes one or more pumping cycles to pressurise the high pressure manifold and therefore recover angular kinetic energy from the electricity generator rotor which can later be used to reaccelerate the electricity generator rotor to the correct operating speed for an electricity grid. Overall energy efficiency is increased and the minimum operating high pressure manifold pressure may be reduced as a result.

Device for controlling torque output of wind turbine blades

Номер: US20160108891A1
Автор: Kuei-Jen Cheng
Принадлежит: Institute of Nuclear Energy Research

The present invention is a device for controlling torque output of wind turbine blades, which can effectively keep the torque output of the blades of a wind turbine in constant and maintain the output stability of the wind turbine further. The present invention does not need any external power input and measurement signal generated from other devices and is a fully passive device which keeps the output of a wind turbine in constant. When the wind speed varies in the rated range, the present invention would adjust the pitch angle of the blades correspondingly and keep the output of a wind turbine in constant. When the wind speed is not in the rated range, the present invention would stop the rotation of the blades, so the output stability of the wind turbine can be kept, and the durability of the wind turbine can also be maintained.
