<p>A power converter device that interchanges power between a first A. C. system (1A) and a second A. C. system (1B), including an externally commutated power converter (5A) controlled such that the D. C. voltage of a D. C. line (8) tracks a reference value, a voltage type self-commutated power converter (6) which converts the output D. C. power of the externally commutated power converter (5A) to A. C. power under pulse width control and supplies the converted A. C. power to the second A. C. system (1B), interchange power control means (51) for controlling the phase difference angle of the voltage on the A. C. side of the voltage type self-commutated power converter and the voltage of the second A. C. system such that the interchange tracks a rereference value, and reactive power control means (52) for controlling the control factor of the pulse width control such that the reactive power generated by the voltage type self-commutated power converter (6) tracks another reference value.</p> |
