Abstract	The paper describes new topology of a generation system that consists of wound rotor synchronous generator and parallel connected power electronic converter. The wound rotor synchronous generator operates as AC voltage source whereas the power electronic converter as fully controllable current source. The converter with embedded energy storage delivers active and reactive power. The first main role of the converter is to deliver reactive power, what results in zero reactive power demanded from the synchronous generator. Thus the synchronous generator moves from cosφ = 0.8 to cosφ = 1. So if the generator keeps its rated current and unity power factor than its active power rises about 25%. Moreover the operation with cosφ = 1 results in significant reduction of its excitation current. Additionally the ability of quick production of the active and reactive power, by the parallel connected converter, keeps voltage and frequency stability in transients and so it permits to accept step load. Such a generation system that consists of the wound rotor synchronous generator, the parallel power electronic converter and common control of power flow is called “Synchrogenverter”. Paper presents theory and computer simulation study related to high power Synchrogenverter operating off grid (autonomously).
