  • Patent number: 11951802
    Abstract: A method of controlling heating of a hybrid electric vehicle is provided. The method includes receiving a heating request from a driver; determining whether an entry condition of pre-FATC engine ON request (PFEOR) control is satisfied; checking whether the vehicle is capable of entering a HEV mode; determining whether the vehicle enters an idle mode for the PFEOR control; issuing a command for a target engine torque value and a target revolutions per minute for the idle mode to an engine control unit (ECU) from a hybrid control unit (HCU); and performing an engine idle speed control along with engine ON based on the command.

  • Patent number: 10215058
    Abstract: Discloses is a turbine power generation system having an emergency operation means and an emergency operation method therefor that are capable of controlling excess heat accumulated during emergency operation, and recycling the accumulated heat. A turbine power generation system includes: an inlet sensor part including a thermometer, a pressure gauge, and a flowmeter that are installed between the heater and the inlet valve and; an emergency discharge part including a branch pipe connected to the steam, and a heat control means installed on the branch pipe. Accordingly, the system and the method are capable of reducing a heat overload during an emergency operation by transferring a heat amount exchanged in the heat storage device to the heat consuming facility, minimizing thermal consumption by recycling the same, and preventing various problems caused by stopping an operation of the turbine power generation system.

  • Publication number: 20180266249
    Abstract: Disclosed is a steam turbine capable of reducing the load of a bearing supporting a turbine shaft transmitting rotational driving force of a plurality of nozzle-equipped rotary bodies arranged in multiple stages. The steam turbine includes a housing (110); a turbine shaft (120) pivotably supported by a bearing (121) in the housing; and a plurality of dish-shaped nozzle-equipped rotary bodies (130) integrally combined with the turbine shaft (120), provided with one or more nozzle holes (131) from which working fluid is ejected so that the nozzle rotations bodies (130) can be rotated, and stacked in an axial direction of the turbine shaft (120). The nozzle hole (131) is inclined with respect to a normal direction n of the periphery surface of the nozzle-equipped rotary body (130) and is inclined toward an axial direction c of the turbine shaft (120).
