  • Publication number: 20240117759
    Abstract: A power generation facility in an embodiment includes: a boiler; a high-pressure turbine to which steam generated in the boiler is introduced; a low-pressure turbine provided downstream of the high-pressure turbine; and a condenser that condenses steam discharged from the low-pressure turbine. The power generation facility further includes: a feed pipe that leads feedwater in the condenser to the boiler; a heat storage and steam generation device that has a heat storage function that uses surplus energy generated in an own system to store heat, and a steam generation function that has part of feedwater led by the feed pipe introduced thereinto and turns the feedwater into steam by the stored heat; and a steam supply pipe that supplies steam generated in the heat storage and steam generation device to an own system.

  • Publication number: 20220337067
    Abstract: A power control apparatus of an embodiment controls power to be output to a power system from a power station including a power generation unit, and a power storage unit. The power control apparatus includes a power generation control unit, a power storage control unit, and a cooperation control unit. The power generation control unit controls an output of the power generation unit based on a power generation set value. The power storage control unit controls an output of the power storage unit based on a power storage set value. The cooperation control unit outputs the power generation set value to the power generation control unit and outputs the power storage set value to the power storage control unit based on a power demand amount of the power system so as to make the power generation unit and the power storage unit operate in a cooperative manner.

  • Publication number: 20150184553
    Abstract: According to one embodiment, a controlling apparatus is a controlling apparatus to control a combined cycle power plant that includes at least a plurality of units, each of the units including a gas turbine; an heat recovering steam generator that recovers heat of exhaust gas from the gas turbine and generates steam from an incorporated drum; and a turbine bypass regulating valve that sends the steam generated from the drum while keeping a predetermined pressure, and comprises a steam header unit that merges together the steam generated from a plurality of the drums; and a steam turbine to which the steam in the steam header unit is supplied. The controlling apparatus comprising a controlling unit that controls a plurality of the turbine bypass regulating valves based on a steam pressure detected in the steam header unit when the plurality of the units are linked.
