<P>PROBLEM TO BE SOLVED: To provide a power plant which can increase power generator output in a short time by a current high efficiency turbine without increasing strength of a turbine to the request of the rapid increase of power generation output. <P>SOLUTION: The power plant includes: a turbine which is driven by steam generated by a steam generator; a condenser which allows the steam discharged from the turbine to become condensation; a plurality of heaters which heat the condensation pressured by a condensate pump; a deaerator which heats and deaerates the heated condensation by the heaters; a deaerator water level adjustment valve which is provided on the upstream side of the condensate system of the deaerator and adjusts water level of the deaerator; and a plurality of turbine bleed valves which extract steam from the respective steps of the turbine and supply extracted steam to the plurality of heaters and the deaerator. The power plant also includes a control device for performing condensation throttling control for a power generator output rapid increase request command, wherein two bleed valves, which are not adjacent, selected from the plurality of the turbine bleed valves and the deaerator water level adjustment valve are closed to constant opening by the constant speed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
