る無効電力制御装置。[Claims for Utility Model Registration] 1. A reactive power compensator is connected to the AC input side of a circulating current power converter that outputs a variable frequency alternating current, and the delayed reactive power of the power converter and the reactive power are compensated for. In the apparatus for controlling the circulating current of the power converter so that the advancing reactive power of the apparatus cancels each other, the reactive power compensator comprises a plurality of banks of capacitors consisting of a fixed capacitor and a variable capacitor, and the capacitors of the plurality of banks The capacitor is set at an output current command value for controlling the output current of the power conversion device and the power factor on the AC input side, or an equivalent amount thereof, to compensate for fluctuations in reactive power on the AC input side. Reactive power control device. 2 Utility Model Registration Scope of Claims 1. The device according to claim 1, wherein the fixed capacitor is a capacitor determined by the output current command value, the value of which is proportional to the ratio of the output current command value to the rated current, Further, the variable capacitor is a capacitor determined by the power factor or its equivalent, and the value thereof is set to be proportional to the square of the ratio of the output current command value to the rated current. reactive power control device.
