<P>PROBLEM TO BE SOLVED: To continue power transmission/reception by controlling a power converter 1 with high reliability without breaking an AC voltage even if the impedance of an AC power system 2 abruptly increases, in a control device for the power converter 1 that controls power transmission by connecting an AC power system 2 and a DC power system 6 by the power converter 1. <P>SOLUTION: The increase of the inductance component is detected by detecting the increase of the current deviation ΔI between a current at the AC side of the power converter 1 and a command value, and an effective power command value PsO* is switched to a reduction command value Ps1* from a command value Ps* at normal driving, thus reducing a command value IP* of an effective current. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
