This paper presents the operation and the results of tests of the variable speed integrated generator and power electronic system VSIG in both autonomous and grid connected modes. The distorted AC grid voltage produces nonsinusoidal current of the converter output capacitor low pass filter. The control described in this paper compensates for the harmonic current and then the grid is fed by sinusoidal current. The variable speed generation system may be useful for distributed generation.
