"textContent": "Power-generation plant equipment (1) of the present invention is provided with a steam-flow-volume adjusting valve (20) that is provided in a superheated-steam pipe (30) on the upstream side of a steam turbine (7). During startup of the steam turbine (7), a controller of the power-generation plant equipment (1) increases a degree of opening of the steam-flow-volume adjusting valve (20) from a closed position, thus increasing the frequencies of the steam turbine (7) and an exhaust-heat-recovery generator (10); and, after the frequency of the exhaust-heat-recovery generator (10) reaches the frequency of a grid (40), the controller connects an exhaust-heat-recovery-side breaker (26) to supply power to the grid (40), and also sets the degree of opening of the steam-flow-volume adjusting valve (20) to a substantially fully-open position, thus, operating the steam turbine (7) depending on the frequency of the grid (40).",
