DISTRIBUTED MONITORING AND CONTROL SYSTEM FOR POWER GRID

摘要

PPROBLEM TO BE SOLVED: To provide a distributed monitoring and control system for power grid capable of quickly reflecting a maintenance database generated by a monitoring and control system on a backup system, with no intervention of an external storage device. PSOLUTION: A maintenance calculator 12 of a monitoring and control system 1 generates a maintenance database 121 of a new generation by using a maintenance database generating means 122 when a facility is changed. A transmission data file 141 in which the maintenance database 122 and an operating database 111 are made into a single file is generated by a transmission data file generating means 124. After testing, it is transmitted to a backup system 2. A maintenance calculator 22 on the backup system 2 side restores it using a restoring means 223, for switching a database.
