<P>PROBLEM TO BE SOLVED: To provide an integrated solar combined cycle system capable of quickly suppressing a decrease in steam temperature without burning a new fossil fuel, even when there arises a sudden decrease in solar heat energy. <P>SOLUTION: An integrated solar combined cycle system includes a solar heat collector 100 for collecting solar heat and generating solar heat steam, a gas turbine 2, a gas turbine waste heat recovery boiler 9, and a steam turbine 10. The solar heat steam is decreased in temperature by a solar heat steam desuperheater 42 under a normal condition, a temperature decrease is stopped or a temperature decrease rate is reduced when the solar heat steam temperature falls for a sudden weather change or the like, the solar heat steam is made to interflow with a steam generated by a high-pressure drum 18 or exit steam of a primary superheater 20, and main steam temperature control by a main steam temperature control valve 30 is further exerted so that the main steam which is controlled to be a predetermined temperature is supplied to the steam turbine. <P>COPYRIGHT: (C)2013,JPO&INPIT |
