When the mail transmission / reception unit 2e determines that the mail received from the outside is a browsing request for the contents recorded in the bulletin board unit 2f, the browsing request contents are read from the stored contents of the bulletin board unit 2f and the bulletin board browsing request is issued. I will send it back to the mobile phone that did. The bulletin board section 2f stores the received mail information in chronological order. The operation of each component other than the above is the same as that of the first embodiment.

Next, the operation of the protection control device 21A (22A, ..., 2NA) will be described by taking the case where a device abnormality occurs as an example. When the protection control calculation unit 2b detects an abnormality of its own device by the constant monitoring / inspection function, the protection control calculation unit 2b passes the device abnormality information to the transmission processing unit 2c and at the same time passes the device abnormality information to the mail transmitting / receiving unit 2e. The e-mail transmission / reception unit 2e selects the mobile phone number list according to the content / degree of the received device abnormality information,
The device abnormality information mail is sent to each maintenance person and maintenance manager according to the mobile phone number list. At the same time, the mail transmitting / receiving unit 2e writes the device abnormality information in the bulletin board unit 2f.

The maintenance staff who has received the device abnormality information carries out maintenance work according to the contents and sequentially sends the contents by mail to the corresponding device. The mail transmission / reception unit 2e that has received the response work information mail from the maintenance staff writes the received maintenance response work information on the bulletin board unit 2f. For example, write down the date / time and the name of the person in charge to move / arrive to the abnormal substation, contact the equipment manufacturer, request the arrangement / delivery of necessary supplies, and complete the restoration work at the abnormal substation. 4). The maintenance manager accesses the bulletin board section 26 of the device to check the progress of maintenance work.

If the maintenance work is not completed within one's working hours, it will be handed over to the next worker. However, the maintenance person who has taken over will access the bulletin board section 2f of the device, which causes a work factor. It is possible to check the occurrence status of equipment failure and the progress of maintenance work at any time. Further, the maintenance person who has taken over writes his / her work content on the bulletin board section 2f.

According to this embodiment, since the mail arrives directly from the power system control and protection system to the mobile phone normally owned by each maintenance staff, the time for information transmission can be shortened and the transmission work can be automated. The progress of the work can be disclosed to people other than the maintenance staff who are actually working.

In this embodiment, the transmission means is a mobile phone mail, but it is also possible to use a PHS, public line telephone, leased line telephone or the like.
