Using the steam turbines with bypass steam distribution at CCGT for primary frequency control

The system of bypass regulation of the steam turbine for the more effective participation in primary frequency control is examined. Power and relative internal efficiency ratio of turbine with bypass steam distribution for various steam consumptions are calculated. It is shown that the steam turbine...

Summary:The system of bypass regulation of the steam turbine for the more effective participation in primary frequency control is examined. Power and relative internal efficiency ratio of turbine with bypass steam distribution for various steam consumptions are calculated. It is shown that the steam turbine with bypass steam distribution in the combined-cycle plant in the hot standby mode with reduced power (to provide power reserve) provides a higher efficiency than when the steam is throttled in the control valve without bypass steam distribution. In addition, power change of the steam turbine with bypass steam distribution provides greater acceleration compared to the operation at the sliding steam pressure and the opportunity of overloading the turbine to the required power level.
