<p><P>PROBLEM TO BE SOLVED: To provide a facility monitoring device, which determines, in the case that a preliminarily specified state change occurs in a power facility, and a state change of relevant apparatuses occurs subsequently, whether the change of the relevant apparatuses follows a preliminarily estimated sequence or not, and determines occurrence of abnormality such as failure in case that it does not follow the sequence. <P>SOLUTION: State changes of other relevant apparatuses resulted from a specified state change are preliminarily stored in a database 23 as sequence information. If the specified state change actually occurs, sequence information for another relevant apparatus inputted to an input part 21 is compared with the actual state change in a determination processing part 22. Accordingly, since whether the actual state change is resulted from the preliminarily specified state change or from others such as failure can be automatically and instantaneously discriminated and determined, high-level monitoring can be performed as a facility monitoring system. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
