1. A combined cycle power generation facility comprising:
a gas turbine;
a first heat recovery steam generator including a first steam generation part which uses a heat quantity of an exhaust gas from the gas turbine to generate steam, and a reheat part which reheats steam;
a first steam turbine to which the steam generated by the first steam generation part is introduced;
a combustor which combusts hydrogen and oxygen;
a reheat steam pipe connecting a steam outlet of the first steam turbine and the combustor with the reheat part interposed therebetween;
a second steam turbine which is coupled to the combustor and to which steam discharged from the combustor is introduced;
a second heat recovery steam generator including a second steam generation part which uses a heat quantity of steam discharged from the second steam turbine to generate steam;
a third steam turbine to which the steam generated by the second steam generation part is introduced; and
a condenser which changes steam discharged from the third steam turbine into condensed water.
