Abstract:
1. A method of controlling a compressor turbine motor train, having a compressor and a turbine operatively coupled to the compressor, the method comprising: receiving an input signal in a compressor control system; receiving a feedback signal in an electrical grid management system; outputting a speed control signal from the compressor control system; outputting one or more command signals from the electrical grid management system; receiving the speed control signal and the one of more command signals in a turbine control system; receiving the one or more command signals in the compressor control system; outputting a drive command signal from the turbine control system; receiving the drive command signal and the one or more command signals in a drive control system; and adjusting a speed and a load of the compressor and adjusting a fuel flow into the turbine, wherein the speed and the load of the compressor and the fuel flow to the turbine are operational parameters of the compressor turbine motor train and adjustments to the speed and the load of the compressor and the fuel flow to the turbine are based on any of said input or said feedback signals to stabilize at least one of a frequency and a voltage of an electrical grid.
