Abstract: <P>PROBLEM TO BE SOLVED: To prevent degradation in transition followability in a reactive power compensation device by minimizing delays in detection of a reactive positive-phase component and a reactive negative-phase component of a power system.  <P>SOLUTION: When the respective positive-phase components and the negative-phase components are separated and detected from a three-phase load current as a DC amount by respectively performing positive-phase vector rotation using a positive-phase vector calculator 12 and negative-phase vector rotation using a negative-phase vector computer 13 respectively after three-phase electric amount such as the three-phase load current is converted to two-phase amount by a converter 11, the negative-phase components and the positive-phase components appear in the respective outputs of the computers 12, 13 as frequency ripples which are twice those of the system. Frequency ripples which are twice those of the system are extracted using hand-pass filters 14a-14c, and computed by the outputs of the computers 12, 13 respectively to minimize delays, thus removing the ripples.  <P>COPYRIGHT: (C)2007,JPO&INPIT
