  • Patent number: 10865773
    Abstract: A method for compensating for flicker induced by a wind turbine power system connected to a power grid includes operating a power converter of the wind turbine power system based on a nominal reactive current command and a nominal torque command. In response to receiving a periodic torque command modifier, the method includes determining a reactive current command modifier for the power converter based on one or more operational parameters of the wind turbine power system and/or the power grid and the torque command modifier. The method also includes simultaneously modifying the nominal reactive current command as a function of the reactive current command modifier and the nominal torque command as a function of the torque command modifier. Accordingly, modifying the nominal torque command causes low-frequency voltage variations in the power grid and simultaneously modifying the reactive current command attenuates the low-frequency voltage variations.

  • Patent number: 10865812
    Abstract: In a hydraulic control device, when it is detected that a pressure of first oil (output pressure) detected by an output pressure sensor pulsates, a transmission control unit as a TCU stops driving of a second pump or decreases a rotation number of the second pump as a first operation. Alternatively, when it is detected that the output pressure pulsates, the TCU increases the rotation number of the second pump to a rotation number (for example, maximum rotation number) that is higher than a target rotation number as a second operation.

  • Patent number: 10865814
    Abstract: A hydraulic actuator includes a switching part that is provided with an oil passage for sending pressurized oil generated by a hydraulic pump to a tool and returning return oil from the tool to the hydraulic pump. The switching part switches a route of at least one of the pressurized oil and the return oil. The switching part includes an operating portion (for example, an operation knob) and an axis portion (for example, a spool) that advances or retreats when the operating portion is turned. When the operating portion is turned, the axis portion advances or retreats in a direction orthogonal to a direction of turning the operating portion, whereby the route of the oil passage is switched.

  • Patent number: 10865815
    Abstract: A screw-threaded working cylinder includes a tubular cylinder that an end region. The end region has a first thread. The end region has a tapered wall section and the tapered wall section has an axial annular surface. A closure has a second thread and the closure is screwed by the second thread into the first thread in a final mounting position. The closure has a mating axial annular surface. The axial annular surface and the mating axial annular surface are pressed in a positive fitting contact to one another in the final mounting position for defining a pressure contact surface. The pressure contact surface defines a sealing plane, and a surface pressure in an area of the pressure contact surface that causes a deformation of the tubular cylinder and the closure. The deformation occurs within an elastic limit over a range from zero applied pressure to a maximum permissible pressure by a pressure medium for the working cylinder. A piston unit is accommodated in the tubular cylinder.

  • Patent number: 10865817
    Abstract: A valve positioner for use on a process control valve or “valve assembly.” The process control valve may include a pneumatic actuator and a valve having a closure member coupled with the pneumatic actuator and moveable relative to a seat. The valve positioner may couple to the pneumatic actuator to provide a pneumatic signal to set a position of the closure member relative to the seat. An accelerometer may couple with the valve positioner. The accelerometer may generate data in response to orientation of the valve positioner. In one implementation, the configurations can use this data to ensure proper visualization of data on a display. The data also permits the device to properly manage operating modes, like tight shut-off or fully-opened mode, that may prevail due to orientation issues that cause defects in a measured position for a closure member that regulates flow of material through the valve assembly.
