Abstract
A reactive power compensator includes a plurality of phase clusters each including a plurality of cells, and a controller configured to control the plurality of phase clusters. When an energy error is generated in each of the plurality of phase clusters, the controller performs control to compensate for the energy error by generating an offset signal having a zero sequence component based on an error energy value of each of the plurality of phase clusters.
