摘要： There is provided a pitch control system (210) for controlling a pitch force system (220) for pitching a blade (103) of a wind turbine (100), the pitch control system (210) being arranged for activating (682) an auxiliary pitch force subsystem (224) at an initiation point in time where a main pitch force is sufficient to pitch the blade (103) into a target pitch value. An advantage thereof may be that tracking of a target pitch value may be improved and the impact on the pitch force system (220) may be reduced. In aspects, there is furthermore presented a hydraulic pitch system (206), a wind turbine (100), a method and a computer program product.

摘要： A method of converting air internal energy into useful kinetic energy is based on air flowing through substantially convergent nozzle, which accelerates the air as the cross section of the nozzle decreases thus increasing the air kinetic energy. The increment of the kinetic energy equals to the decrement of air internal energy, i.e., air temperature. Within said nozzle a turbine is placed to convert airflow kinetic energy into mechanical energy that transformed into electrical energy or transferred into a gearbox to provide driving moment. Devices uses this method could use natural wind as airflow source or artificial airflow means. Devices, which incorporate means to create airflow artificially, can be used as engines for land, sea and flying vehicle. Since air temperature drops within the nozzle, moisture condensation exists and liquid water can be accumulated for further use.

摘要： A wind-capturing electrical generator device (100) comprising a plurality of generators is driven by wind created by traffic passing in close proximity at high speeds. The device (100) uses horizontally or vertically mounted Savonius-type or helical-turbine-type vanes (104) attached to electrical generators (102) in order to capture the wind and produce electrical energy. A plurality of electrical generator devices (100) may be mounted in a configuration such that they are in close proximity to vehicular passageways (e.g., highway overpasses, tunnels, or train rails). The wind created by the traffic is used to rotate the vanes (104) and their attached generators (102) in order to produce electrical energy.

摘要： A helical turbine assembly capable of providing high speed unidirectional rotation under a multidirectional ultra low-head fluid flow is disclosed. The assembly comprises an array of helical turbine units or modules arranged, vertically or horizontally, to harness, for example, water or wind power. Each turbine unit or module comprises a plurality of helical blades having an airfoil profile. The modules for wind power may be mounted to rotatable shafts supported by lightweight structures anchored by guy wires to the ground. The helical turbine can also provide ship propulsion by utilizing the power of ocean waves. In a further embodiment, a cylindrical distributor is provided in the helical turbine to channel the fluid flow to the blades of the turbine, thereby increasing efficiency and power output. The helical turbine with distributor may be used to lift or lower a body either being submerged into a fast stream or dragged in the fluid. The turbine may also include two or more rings of helical blades to increase torque and power output.
