摘要： A multistage wind turbine or network of wind turbines with improved and optimized wind-directing, wind-shaping, and wind-power conversion features is disclosed. The shapes of these features directly affect the ability of the multistage wind turbine to use the power of moving air, to spin a rotor and create torque on a rotor shaft to generate electrical, thermal and/or other forms of energy. The wind-power-conversion mechanical efficiency described significantly improves upon previous designs by conversion of wind energy into electrical power at a superior price-to-performance ratio compared with existing alternative energy technologies.

摘要： A hydroelectric power generation system includes a water turbine, a generator connected to the water turbine, and a controller. The water turbine is arranged in a flow path through which a fluid flows. The controller performs a pressure control by controlling the generator to regulate a pressure of the fluid downstream of the water turbine. The pressure control includes a first control regulating the pressure in parallel with a regenerative operation of the generator, and a second control regulating the pressure in parallel with a power running operation of the generator.

摘要： The invention provides a wind turbine including a nacelle, a rotor having at least one blade attached to a hub, and an electrical supply structure for supplying electrical power from the nacelle to the rotor. The rotor is rotatably connected to the nacelle about an axis of rotation. The supply structure comprises a switch which has a connected mode in which the nacelle and the rotor are electrically connected, and a disconnected mode in which the nacelle and the rotor are electrically disconnected. Furthermore, the switch is adapted to change from the disconnected mode to the connected mode when the rotor does not rotate.

摘要： Systems and methods for controlling a wind pitch adjustment system associated with a wind turbine system are disclosed. In one embodiment, the wind pitch adjustment system can include a power supply configured to convert an alternating current input signal into a direct current voltage, a controller configured to receive a signal from the power supply, and to provide one or more control commands to a pitch adjustment motor, and a surge stopping device comprising a switching element coupled between the power supply and the controller. The surge stopping device is configured to monitor an input voltage from a grid and to drive the switching element based at least in part on the monitored input voltage, such that the switching element is configured to block current flow through the switching element to the controller when the monitored input voltage is above a voltage threshold.
