PROBLEM TO BE SOLVED: To disconnect or connect at least one arbitrary stationary inverter in operation from or to a load by a method, wherein a group of stationary inverters which are connected in parallel to each other are variably allocated to a plurality of loads by an upper hierarchy control or regulating means. SOLUTION: Total current regulators 63 and 73 regulate the total current of stationary inverters 1, 2 and 3, which is allocated to a load A61 and a lead B71. Modulators 64 and 74 generate drive signals of the respective stationary inverters 1, 2 and 3, in accordance with various conditions set by the total current regulators 63 and 73. A flexible control power control machine 8 sets an input crossbar distributor 4 and an output crossbar distributor 5, according to current demands and distributes and allocates the load A61 and the load B71 to the stationary inverters 1, 2 and 3. Furthermore, controls the output currents of the respective stationary inverters 1, 2 and 3 in response to predetermined target current values via equivalent regulators 65 and 75. |
