Abstract

PURPOSE: To make a compensation control operable in good response to the both of lagging an leading reactive power, by the method in a manner with one converter keeping the current in DC reactor at constant level with another converter operating the compensation control of the reactive power.
CONSTITUTION: The system, comprising those from a detector 8 to a pulse amplifier 13, makes such action that, with a load current detected correspondingly to this detection to process an operation of the reactive power to be compensated, its conversion is made into a designated value current I1' and a comparison made with a detected current value I1, on the basis of their difference, the phase control angle of a converter 1 is specified to make a reactive power compensation value coinciding with the required value. On the other hand, the system, comprising those from a current setter 14 to a pulse amplifier 18, makes an action such that, the current detected value I1 at a converter 2 side is subtracted from a constant current set value Id' to transmit a current designated value for the converter 1, with the before said compared with a current detected value I2, and the converter 2 is controlled so as to provide the equality and to obtain a constant DC reactor current. In this way, a compensation regulation can be made in good response to the both lagging and leading.
