Abstract: A power supply system includes: a synchronous generator connected to a three-phase power distribution system that is connected to a consumer load; an inverter that is connected to the power distribution system, supplies power to the consumer load, and compensates for unbalanced current of the synchronous generator; and a control device that generates a gate command for controlling the inverter. The control device: generates, based on a three-phase voltage and current output from the inverter, a target output voltage which is an amplitude of a vector in a complex plane combining voltages of three phases, and a target output phase which is a phase of the vector in the complex plane combining the voltages of three phases; generates a first compensation voltage, based on a current negative-phase-sequence component relating to the synchronous generator; and generates a gate command from the generated values.
