PROBLEM TO BE SOLVED: To attain continuously variable control for both phase angle and voltage using induction phase-shifters so as to provide controlled power flexibility irrespective of both frequencies, phases or voltages in the linkage of a power system. SOLUTION: The output voltage phases of a plurality of induction phase- shifters are controlled independently and vector-composited thereby arbitrarily controlling the voltage and phase of composited output voltage. By using a plurality of conventional phase-shifters which control only phase rotation, the magnitude of voltage as well as phase is controlled without the total capacity of the phase-shifters being changed, thus it is possible to make compensation for voltage fluctuations in the linkage system. |
