PROBLEM TO BE SOLVED: To operate a plurality of small-size AC gas turbogenerators in parallel without synchronous operation equipment by a method wherein the respective outputs of the generators are rectified by a converter device and a plurality of DC outputs obtained from the converter device are synthesized. SOLUTION: 3-phase AC outputs A1, A2 and A3 are inputted to a converter circuit 4 and respectively rectified by the converter circuit 4 to obtain corresponding rectified outputs (DC outputs) C1, C2 and C3. A synthesizer which synthesizes the rectified outputs C1, C2 and C3 obtained from the rectifiers 41, 42 and 43 of the converter circuit 4 respectively consists of a DC circuit 5. The rectified outputs C1, C2 and C3 are made to pass through a low-pass filter circuit composed of a capacitor 51 and a reactor 52 to be synthesized while only their positive or negative polarities are matched with each other. The synthesized DC output D is supplied to an inverter device 6 and a part of the DC output D is used to charge a battery 53 provided in the synthesizer. The battery 53 supplies an electrical energy corresponding to the load fluctuation and is operated as a partial energy supply for the sudden increase of a load. |
