Abstract
CONTROL DEVICE FOR ACTIVE FILTER Disclosed is a control device (71) controlling an operation of an active filter (6) 5 which is connected in parallel with a load (2) at an installation point (P) with respect to an AC power source (1) and which supplies a compensation current (Ic) to the installation point (P) so as to compensate for a harmonic component of a load current (Io) flowing through the load (2). The control device (71) includes: a dq converter (703) converting the load current (Io) into a component of a d-axis current and a component of a q-axis current; a high -pass filter 10 (704, 705) extracting a harmonic component from at least the component of the q-axis current output from the dq converter; a multiplier (716) outputting a result obtained by multiplying a component of a d-axis current output from the high-pass filter (704) by a compensation rate (Kd) as a current command value (id*); and a multiplier (717) outputting a result obtained by multiplying the component of the q-axis current output from the dq converter (703) or a 15 component of a q-axis current output from the high-pass filter (705) by a compensation rate (Kq) as a current command value (iq*). The compensation rate (Kq) of the q-axis current in the multipliers (716, 717) is adjustable. FIG. 1 20
