<p>There is provided an alternating current rotating machine control device wherein, by sharing information among a plurality of power conversion devices and other accompanying instruments, and thus strengthening an alternating current rotating machine drive linkage, the optimization of a whole power conversion system is facilitated. A power conversion system has a distributed configuration of a top level control device (10) configuring a master station, a plurality of power conversion devices (11 to 13), accompanying information instruments (various kinds of sensor instrument such as a temperature sensor (14) and a pressure sensor (15)), and the like. The top level control device (10) is connected to the power conversion devices (11 and 12) by a first communication line (22). Furthermore, the power conversion devices (11 and 12) are provided with two or more communication functions, and are connected to the remaining power conversion device (13), temperature sensor (14), and pressure sensor (15) by a second communication line (23).</p> |
