Abstract

PURPOSE: To make a compensation control operable in good response to the both of lagging and leading reactive power, by the method in a manner with one converter keeping the current in or the voltage across both ends of DC reactor at constant level with another converter operating the compensation control of the reactive power.
CONSTITUTION: A detector 8 detects a load current instantaneous value iL to process an operation of the reactive power, and a detector 9 detects an output current instantaneous value ic to process an operation of the reactive power that corresponds to said value ic, with both of those outputs processed a subtraction by an addition element 10 to produce a difference signal. With the difference signal used for a control deviation, the phase control angle +α1 of a converter 1 is controlled through a pulse amplifier 13. On the other hand, an addition element 15 makes a subtraction of DC reactor current detected value Id from a constant current set value Id', fed from a current setter, to transmit a command value, with said command value controlling the phase control angle -α2 of a converter 2 through a pulse amplifier 18, in this way, the current ID in a DC reactor 3 is kept at the constant value Id', thus capable of operting the compensation control in good response to the both lagging and leading.
