Title:
CONTROL DEVICE AND POWER CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/234884
Kind Code:
A1
Abstract:
This control device (10) for controlling a power supply (20) connected to an AC system is provided with: a frequency control unit (201) for controlling the frequency of the power supply operating with a constant-voltage/constant-frequency control scheme; a power calculation unit (203) which, when the frequency control unit varies the frequency of the power supply, calculates the variation value of active power output from the power supply; a calculation unit (205) for calculating the frequency characteristic constant of the AC system on the basis of the variation value of the frequency of the power supply and the variation value of the active power output from the power supply; and a selection unit (207) for selecting a control scheme of the power supply on the basis of the frequency characteristic constant of the AC system.
