Zusammenfassung:	PROBLEM TO BE SOLVED: To estimate a vibration cause of a distributed power source simply with high accuracy. SOLUTION: In this distributed power source vibration diagnosis system, the vibration of equipment constituting the distributed power source 14 is measured to diagnose an abnormality of the distributed power source. A vibration measuring means 1 measures the vibration of the equipment. A determination means 9 determines a vibration abnormality by comparing a measurement signal measured by the vibration measuring means with a reference value determined beforehand. A test operation condition determination means 11 determines automatically a test operation condition based on the determination result by the determination means. An automatic operation means 12 operates automatically the distributed power source in the determined test operation condition. The determination means determines the vibration abnormality based on a vibration state change occurring when the operation condition is changed. COPYRIGHT: (C)2005,JPO&NCIPI
