Title:
POWER SUPPLY SYSTEM AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2017/163831
Kind Code:
A1
Abstract:
A power supply system (1) is provided with: a synchronous power generator (11) connected to a three-phase power distribution system (40) connected to a customer load (30); an inverter (21) connected to the power distribution system (40), supplying power to the customer load (30), and compensating an unbalanced current in the synchronous power generator (11); and a control device (100) for generating a gate command for controlling the inverter (21). The control device (100) generates, on the basis of three-phase voltage and current output from the inverter (21), a target output voltage that is the amplitude of a vector on a complex plane in which three-phase voltages are lumped together and a target output phase that is the phase of a vector on the complex plane in which the three-phase voltages are lumped together, and generates a first compensation voltage on the basis of a current reverse-phase component of the synchronous power generator (11). The control device (100) generates the gate command from the target output voltage, the target output phase, and the first compensation voltage.
