Beschreibung
Zusammenfassung:	Proposed is a synchronous control method for a power conversion unit. The method allows the synchronous characteristic of a conventional generator to be emulated, the implementation of said method being based on a traditional current controller and on the control voltage generated. By defining a virtual electromotive force and the system control voltage, the method implements a synchronisation structure to maintain the stability of the system and generate a synchronous compensation current, thereby promoting the stability of the frequency and the voltage at the point of common coupling of the power conversion unit. The method also enables control and adjustment of the basic parameters of the system, inertia, the damping factor and the virtual impedance value, allowing the mains voltage and frequency to be improved and supported dynamically.
