Effectiveness of Large Power Reduction for a Combined-Cycle Power Plant with Several Gas Turbines and One Steam Turbine and Some of the Shutdown Equipment Used as Hot Reserve

详细

The change in the structure of generating capacities and the commissioning of combined-cycle power units with efficiency much higher than that of the best steam-power units motivated designing these units mainly for baseloads. However, the recent market changes in the generating capacities of Russia and other countries have required extending the normal operating range of CCPPs with HRSGs and accelerating hot start-ups after short (up to 8 – 10 hours) downtimes.
