Title:
DYNAMO-ELECTRIC MACHINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/029407
Kind Code:
A1
Abstract:
A dynamo-electric machine control device (10) controls the drive of a rotary electric machine (80) having motor windings (180, 280). A plurality of control units (150, 250) have drive control units (151, 251), mode selection units (152, 252), abnormality monitoring units (155, 255), and storage units (156, 256), and can communicate with each other. The mode selection units (152, 252) use a normal drive mode as a cooperative drive mode, and when an incoordination abnormality which is a communication abnormality or a synchronization abnormality between the control units (150, 250) is detected, the drive mode is switched from the cooperative drive mode to an independent drive mode. Also, after shifting to the independent drive mode due to the incoordination abnormality, when an other power system stoppage is confirmed based on other power system monitoring information, the mode selection units (152, 252) switch the drive mode from the independent drive mode to a backup mode.
