SYSTEM AND METHOD FOR MONITORING MAGNETIC GEAR TYPE POWER GENERATION DEVICE

PROBLEM TO BE SOLVED: To provide a system and a method for monitoring a magnetic gear type power generation device capable of quickly and properly informing abnormal portions during an abnormal time.SOLUTION: A system 20 for monitoring a magnetic gear type power generation device in an embodiment comprises: plural power generation side measuring parts 22 for measuring a rotation number of each power generation side rotor 4; and a power generation side abnormality determination part 32 for determining abnormality of the rotation number of each power generation side rotor 4 based on the rotation number of the power generation side rotor 4 measured by the plural power generation side measuring parts 22. The abnormal portions are specified by an abnormal portion specifying part 33 based on existence of the rotation number of each power generation side rotor 4 determined by the power generation side abnormality determination part 32. The abnormal portion specified by the abnormal portion specifying part 33 is informed by an abnormality informing part 34. The abnormal portion specifying part 33 specifies a driving side rotor 3 as an abnormal portion when the power generation side abnormality determination part 32 determines that abnormal rotation numbers exists in the plural power generation side rotors 4 adjacent to each other.
