PROBLEM TO BE SOLVED: To provide a parallel operation control method suitable for the occasion of operating a plurality of voltage-type inverters in parallel, and supplying power to a load. SOLUTION: By causing a control device 26 to perform adjustment computation for making the deviation of a detected value zero by a CT 14 from a detected value by a CT 24, causing a control device 36 to perform adjustment computation for making the deviation of the detected value zero, by the CT 24 from a detected value by a CT 34, causing a control device 46 to perform adjustment computation for making the deviation of the detected value zero, by the CT 34 from a detected value by a CT 44, causing control device 16 to perform adjustment computation for making the deviation of the detected value zero by the CT 44 from the detected value by the CT 14, when operating in parallel a voltage-type inverter composed of reference codes 11-14, 16, a voltage-type inverter composed of reference codes 21-24, 26, a voltage-type inverter composed of reference codes 31-34, 36, and a voltage-type inverter composed of reference codes 41-44, 46, power is supplied to a load 1, suppressing a cross current among the respective voltage-type inverters. |
