Abstract
An external steam turbine main steam startup control valve bypass loop is provided to facilitate a full pressure combined cycle rapid response/fast start powerplant. The main steam startup bypass control loop particularly includes a main steam startup bypass control valve, which allows for the implementation of high efficiency, low pressure drop main steam control valve that otherwise would not be able to handle the severe throttling duty during a full pressure steam turbine startup and enhances the controllability of the steam turbine allowing for the high fidelity controls necessary to minimize steam turbine rotor stresses.
