A control unit controls a first power converter so as to make the speed of a motor/generator coincide with a prescribed speed command. A speed command (N*) set by an upper stream control system is inputted to a smoothing unit of the control unit. In the smoothing unit, the speed command (N*) is smoothed by a first-order lag element, and the rate of change is limited by a rate limiter to a prescribed value or less. For the speed command (Ns*) outputted from the smoothing unit, the difference (ΔN) from the actual speed (N) of the motor/generator is calculated in a difference calculator, a control command (S) based on this difference (ΔN) is generated in a control signal generator, and the first power converter is controlled on the basis of this control command (S). Fluctuations in the supply of power to the electric motor are thereby suppressed.
