  • Patent number: 10320261
    Abstract: For reducing vibrations and noise in electrical machines a rotor is mounted in a magnetic alignment device while a bearing shield is loosely held relative to a stator. The rotor is driven by the stator and vibrations of the rotor are detected. A magnetic alignment device is controlled so as to reduce the vibrations. Finally the bearing shield is fixed to the stator in a position determined by the controlling of the magnetic alignment device. Thus electromagnetic forces are taken into consideration during vibration and noise reduction.

  • Patent number: 10301974
    Abstract: An activation control apparatus permits activating a steam turbine safely at high speed in response to a power generation plant state. A heat source apparatus heats low-temperature fluid to generate high-temperature fluid, and steam generation equipment generates steam by thermal exchange with the high-temperature fluid. A steam turbine is driven by the steam, and an adjustment apparatus adjusts a plant operation amount. A thermal effect amount prediction calculation device calculates a prediction value for a thermal effect amount for use for activation control of the steam turbine, and a changeover device decides, based on a state value of the power generation plant, the sensitivity of the thermal effect amount to a variation of the plant operation amount and outputs a changeover signal in accordance with the sensitivity. Based on the changeover signal, an adjustment device calculates the plant operation amount so as not to exceed a predetermined limit value.

    Abstract: A method for coupling a gas turbine connected to a generator and a steam turbine, wherein the generator has an excitation winding, the excitation of which can be changed by changing an excitation current flowing through the excitation winding, the method having the following steps: a) accelerating and/or decelerating the steam turbine in such a way that the coupling takes place with a target coupling angle; b) if necessary, changing the excitation current such that the excitation of the excitation winding changed in this way leads to a changed polar wheel angle, wherein the polar wheel angle is changed in such a way that the achieving of the target coupling angle is supported. In an analogous method, the polar wheel angle is changed for the purposes of improved decoupling. A corresponding control device is for coupling a gas turbine connected to a generator.

  • Patent number: 9835172
    Abstract: An electrically assisted turbocharger (10) includes an air cooling system for cooling an electric motor (52) housed within a motor chamber (54) in a bearing housing (12). An inlet volute (76) is formed in the bearing housing (12) on a first side of the electric motor (52) and an outlet volute (78) is formed in the bearing housing (12) on a second side of the electric motor (52) opposite from the inlet volute (76). The inlet volute (76) accelerates cooling air that is fed into the inlet volute (76) and directs the cooling air into the motor chamber (54). The cooling air travels in an axial direction through the motor chamber (54) from the inlet volute (76) to the outlet volute (78), thereby cooling the electric motor (52). The outlet volute (78) decelerates the cooling air and directs the cooling air out of the motor chamber (54).

  • Patent number: 9822699
    Abstract: A hybrid turbocharger includes a first power conversion unit to convert a direct-current power into alternating-current power to be output to a generator motor, a smoothing capacitor between direct-current buses, and a control unit that controls the first power conversion unit so as to cause actual generator motor speed to comply with an engine speed command of the generator motor input from an upstream controller during a motoring operation of the generator motor. The control unit changes the engine speed command to a value which is equal to or greater than the actual generator motor speed if the engine speed command of the generator motor is less than the actual generator motor speed and a direct-current bus voltage is equal to or greater than a predetermined first threshold value during the motoring operation. Accordingly, the direct-current bus voltage can be prevented from increasing during the motoring operation.

  • Patent number: 9765755
    Abstract: Described herein is essentially a high-efficiency, hybrid fluid-aeolipile. In operation, this hybrid device is placed in the stream of a moving fluid, preferably air. Energy is extracted from the fluid stream by directing a portion of the stream through and, optionally, around the device. As the fluid-flow moves through the device, it is directed into nozzles. These nozzles, which are free to pivot in a cyclical manner, employ the established phenomenon of “nozzle-effect” to accelerate the velocity of the air-flow passing through them, which is ultimately ejected from each nozzle tip, producing thrust. This thrust, amplified by nozzle-effect, drives the nozzles to pivot around a shared axis. The wind energy, thereby converted into cyclical motion, that may be used to perform useful work, is converted with greater efficiency, than is possible in conventional blade-type wind turbines.
