摘要
A control device (20) for a voltage source converter (15) of a power supporting arrangement (10), where the voltage source converter (15) operates as a virtual synchronous machine. The control device (20) obtains a measured power level of the converter (15), processes the obtained power level using a differential equation of the angular velocity of the virtual synchronous machine in order to obtain a control contribution, provides the phase angle of a physical quantity used to control the converter (15) based on the control contribution, monitors the ability of the converter (15) to act as a virtual synchronous machine, and adjusts the control contribution based on the monitored ability.
