PROBLEM TO BE SOLVED: To provide a facility monitoring device for finding out abnormality of a facility to be monitored on the basis of a sensor output to be used for the monitoring of a state of the facility even under situations in which the state of an environment which affects the sensor output varies.SOLUTION: A monitoring unit 130 constituting a wind power generation facility monitoring device includes: an input processing part 310; a harmony parameter calculation part 320; a classification processing part 330; an abnormality determination part 340; and a transmission/reception processing part 350. The classification processing part 330 classifies respective harmony parameters calculated by the harmony parameter calculation part 320 into a plurality of groups in accordance with an output value from a sensor for detecting a state of an environment. The abnormality determination part 340 determines the presence/absence of abnormality by comparing the harmony parameters classified into the plurality of groups by the classification processing part 330 with the threshold of each harmony parameter set for each group. |
