Information necessary for the restoration work includes the presence or absence of relay lock and power outage requirements. Next, in step SG12, the control unit 18 creates a form related to the recovery work. The form includes a power outage work request and a work confirmation form. Next, in step SG13, the control unit 18 notifies the created form and ends the recovery work procedure process. The created form is notified to the terminal of the department related to the management of the electric power station including the management department terminal 14. When there is the same kind of failure (trouble) response record in the past when creating the form, the failure response result information database 43 is accessed, the failure response result information is referred to, the power failure work request document included in the failure response result information, The work confirmation slip can be reused.

  Next, failure response result report processing will be described. In step SH11 (FIG. 23), the control unit 18 causes the display unit 23 to display an input screen for information related to the restoration work. Information related to restoration work includes defective parts, repair results, causes of occurrence, and concerns. Next, when these pieces of information are input from the input unit 22, in step SH12, the control unit 18 acquires information related to the recovery work. For example, “Bad part: A / D converter for XX wire relay, Occurrence cause: Aged deterioration (aged 24 years), Concern: The target protection device is an aged device and the manufacturer support end target device, so the renewal plan “Weaving into” is entered.

  Next, in step SH13, the control unit 18 updates the failure handling result information database 43 with information related to the restoration work. Next, in step SH14, the control unit 18 notifies the update contents to the terminal of the department related to the management of the electric station including the management department terminal 14, and ends the failure response result reporting process. The repair information registered in the failure response result information database 43 is stored until the equipment is removed. In addition, using the failure response result information, statistics and analysis such as the manufacturer, the aging distribution of the device, the failure site, and the repair response results are created. The analysis result can be searched or output as a form.

  Thus, according to the configuration of this embodiment, the support device 5 refers to the information of each database in the storage device 6 and executes the support processing, so that the response when the protection device fails can be handled smoothly and quickly. And it can contribute to ensure. In particular, the restoration items, test equipment, test circuits, and test methods that differ for each manufacturer and model are centrally managed in each database of the storage device 6, so that it is possible to prevent leaks of work necessary to deal with failures and ensure It can correspond to. In addition, for example, by performing work according to the display content of the display unit 23, anyone can respond accurately and smoothly in the event of a failure of the protective device, regardless of the level of proficiency, without requiring advanced specialized knowledge. It can be carried out. Therefore, the cost required for education and training can be reduced. Further, since the storage device 6 can also be accessed from the portable terminal 15, the management department terminal 14, etc., information related to the failure of the protection device can be shared.
