ABSTRACT:
Systems and methods for synchronizing a gas turbine-driven generator to an AC power system by employing optimal time control theory to directly drive the turbine-generator to a synchronizing point. The fuel commands, synchronization points, and trajectories are selected in view of the need to minimize thermal stress on the turbine hot-gas-path parts, while also minimizing time required for synchronization. Digital computer and analog implementations are disclosed.
