Abstract

PURPOSE: To prevent hunting corresponding to different capacitors by providing a step for operating a throw-in point and an interrupting point based on set values.
CONSTITUTION: An operating section 31 reads in set values from a setting section 30 as well as reactive power and load current detected respectively through a reactive power detecting section 4 and a load current detector 5 and operates a throw-in point QT, an interrupting point QC, interruption current IC, reclosing current IT and reactive factor sinθ. When the load current I increases from below the interruption current IC and exceeds over the reclosing current IT, the process goes to a control step. If the reactive power θ is leading and exceeding over the interruption point QC, an interruption signal is fed to a relay circuit 20 in order to interrupt a specific capacitor. When the reactive power is lagging and exceeding over the throw-in point QT, a specific capacitor is thrown in. Cyclic control is made for identical capacity of capacitors C1-CN while priority control is made for different capacity where throw-in and interruption sequences are reversed, thus preventing the power factor from leading or lagging.
