Abstract
A control unit of a system stabilizing device uses a fluctuation detecting blockfor determining current commands from a system current. A fluctuation detecting unitdetermines, from an active component Iof the system current, a common current command Iwhich is a fluctuation component of the active component I. A first current command creating unitreceives as an input the current command I, and outputs a current command Iwhose signal width is as small as Tand which instantaneously rises and then gradually decreases. A second current command creating unitreceives as an input the current command I, and outputs a current command Iwhich gradually increases for a time Tand then gradually decreases for a time (T-T). The system stabilizing device having short charging and discharging times is controlled by the current command I, while the system stabilizing device having long charging and discharging times is controlled by the current command I, whereby system stabilizing controls can be exercised without interferences. In this manner, even if system stabilizing devices having different charging and discharging characteristics are provided, system stabilizing controls can be effected without interferences.
