Abstract
A power generation plant comprises a plant control device () including two switchable control modes, i.e., a gas-turbine load control mode () and a steam-turbine load control mode (). When the control is performed with the gas-turbine load control mode (), a fuel valve () is controlled based on a load of a whole generator set (), and a steam regulating valve () is controlled based on an exhaust pressure of a steam turbine (). When the control is performed with the steam-turbine load control mode (), the fuel valve () is controlled such that a valve opening degree thereof is maintained constant, and the steam regulating valve () is controlled based on a load of the whole generator set ().
