PURPOSE:To perform the control which is easy to set and uses capacitors different in capacity, by operating the making level and the breaking level based on the set value of a setting means. CONSTITUTION:A CPU 102 reads in the measured reactive power value detected by a reactive power detecting part 101 and operates the reactive power value based on this value and judges whether the reactive power value is advanced or delayed. If it is advanced, it is judged whether the reactive power value exceeds a breaking point set value or not, and a breaking signal is outputted through a relay control part 107 if the reactive power value exceeds the breaking point set value. Capacitors which should be made or broken out of capacitors 62a, 62b, and 62c are determined by the signal from the relay control part 107. Thus, the change of the set value or the like is facilitated, and the control using capacitors different in capacity is possible. |
