  • 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.

  • Patent number: 5041423
    Abstract: New antibiotics of the mureidomycin group have the formula ##STR1##wherein X represents the group ##STR2##and wherein R represents hydrogen, an alkyl group having from 1 to 10 carbon atoms, an alkenyl group having from 2 to 7 carbon atoms, an alkynyl group having from 3 to 7 carbon atoms, an aryl group having from 6 to 10 carbon atoms, an aralkyl group having from 7 to 10 carbon atoms, or one of the said aryl or aralkyl groups substituted with at least one substituent selected from halogen and alkyl groups having from 1 to 5 carbon atoms. The compound in which X represents 8-hydroxy-1,2,3,4-tetrahydroisoquinolin-3-yl is named mureidomycin E and the compound in which X represents 6-hydroxy-1,2,3,4-tetrahydroisoquinolin-3-yl is named mureidomycin F. This group of compounds and their pharmaceutically acceptable esters and salts are useful as antibiotics for the treatment of bacterial infections.
