AI Technical Summary
Technical Problem
In power supply systems with AC and DC generators, load fluctuations cause voltage frequency fluctuations, leading to potential disconnection of the DC power supply device from the AC power generator during autonomous operation.
Method used
A command generation device simulates a virtual power generator using rotor, governor, and AVR models to generate control commands for the DC inverter, matching time constants and droop characteristics with the AC generator, thereby stabilizing the system and sharing load fluctuations.
Benefits of technology
The solution effectively stabilizes the power supply system by preventing disconnection of the DC power supply device and sharing load fluctuations between AC and DC generators, ensuring continuous operation.
