<P>PROBLEM TO BE SOLVED: To provide a controller of an AC rotary machine, which shares information between a plurality of power converters and other additional apparatuses and reinforces a driving linkage of the AC rotary machine so as to facilitate optimization of a whole power conversion system and to provide an operation method of the controller. <P>SOLUTION: The power conversion system is dispersively constituted of a high-order controller 10 constituting a master station; a plurality of power converters 11 to 13; and attached information devices (various sensors such as a temperature sensor 14 and a pressure sensor 15). The high-order controller 10 is connected to the power converters 11 and 12 by a first communication line 22. The power converters 11 and 12 load two or more communication functions and are connected to the remaining power converter 13, the temperature sensor 14 and the pressure sensor 15 by a second communication line 23. <P>COPYRIGHT: (C)2012,JPO&INPIT |
