  • POWER CONVERSION DEVICE CONTROL SYSTEM
    Publication number: 20230087529
    Abstract: A control system is provided for a power conversion system having a power converter that controls a virtual synchronous generator simulating a synchronous generator and interconnected to a power grid. The control system has a virtual synchronous impedance compensation block inputting an output current detection value of the power converter and a set voltage amplitude command value, simulating a voltage drop due to a virtual synchronous impedance, and calculating an output voltage command value and an internal induced voltage according to the simulated voltage drop; a virtual synchronous generator model determining an angular frequency simulating the synchronous generator; and a PCS output voltage control unit performing control so that an output voltage of the power conversion system coincides with the output voltage command value calculated by the virtual synchronous impedance compensation block.
