Abstract
A reactive power compensation apparatus includes one or more phase clusters each comprising a plurality of cells, and a controller controlling the one or more phase clusters. When at least one cell in a specific phase cluster among the one or more phase clusters is faulty, the controller controls a voltage of each cell in each of the remaining phase clusters except for the specific phase cluster to be controlled, using a modulation index.
