As described above, according to the present invention, the processing means based on the equipment diagnosis data and the guidance data such as the cause identification and the recovery support information at the time of abnormality detection of each equipment are shared by the upper system. , The configuration of the monitoring equipment at each substation can be simplified without compromising the function and processing speed of the system, and the monitoring and diagnosis of each substation can be centrally performed by one upper system Becomes Further, since the data processing means further includes a transmitting device for transmitting an abnormality detection signal to the portable communication device when an abnormality is detected, it is possible to notify a maintenance person having a portable communication device such as a pager of the occurrence of the abnormality. Further, the data processing means
By providing a communication interface for extracting information by communication, a maintenance person who has been notified of the occurrence of an abnormality can carry a portable man-machine interface (I / F) such as a notebook computer from an unspecified remote location (23) Is connected to a communication line such as a telephone line to perform communication such as personal computer communication, so that the latest monitoring data of a substation in which an abnormality is detected can be viewed in a place other than the substation. Furthermore, the upper system monitoring device (2) determines the period until the abnormal level is reached based on the information accumulated in the all substation trend data storage device (14) and the mathematical method (abnormal arrival predicting means ( 31) and a storage device (3) in which maintenance support data necessary for avoiding abnormalities is stored in advance.
Provision of 2) enables predictive maintenance before an abnormality is detected. In addition, since the substation monitoring device (1) includes the forced measurement means (41), the man-machine interface (I / F) (9) in the substation or the man-machine interface (I / F) (I / F) (15) ), That is, the setting of the substation, the target device, and the monitoring item, real-time monitoring diagnosis different from the normal measurement cycle can be executed as needed.
