<p>Provided is an alternating-current rotating machine controller, wherein coordinated driving of the alternating-current rotating machine is enhanced by sharing pieces of information among multiple power converters and other auxiliary devices in order to allow the overall electric power conversion system to be optimized easily. The electric power conversion system has a distributed configuration comprising a high-order controller (10), multiple power converters (11-13), auxiliary information instruments (sensor devices of various kinds such as a temperature sensor (14) and a pressure sensor (15)), and the like that constitute a master station. The high-order controller (10) is connected to power converters (11, 12) by means of a first communication line (22). The power converters (11, 12) have 2 or more communication functions and are connected to the remaining power converter (13), the temperature sensor (14), and the pressure sensor (15) by means of a second communication line (23).</p> |
