A microturbine power generating system includes a combustor and a gas compressor that provides a flow of natural gas to a combustor. The flow of natural gas is regulated by varying the speed of the gas compressor to maintain gas compressor discharge pressure at a set point. The system further includes a turbine and an electrical generator that is driven by the turbine during a run mode of operation. A rectifier and a main inverter convert an output of the electrical generator into fixed frequency ac power during the run mode. A secondary inverter operates an electric motor of the gas compressor at the variables speeds during the run mode. During a startup mode, however, the main inverter operates the gas compressor motor, and the secondary inverter operates the electrical generator as a starter motor.
