Abstract
An alternating current rotating machine control device that shares information among power conversion devices and instruments. A power conversion system has a top level control device, a master station, multiple power conversion devices, instruments (such as a temperature sensor and a pressure sensor), and the like. The top level control device is connected to two of the power conversion devices by a first communication line. These power conversion devices have two or more communication functions, and are connected to a remaining power conversion device, a temperature sensor, and a pressure sensor by a second communication line.
