TRANSFORMER SUBSTATION AUTOMATION SYSTEM

摘要

An SC includes a determination database storing determination data. The SC includes a specific-event-occurrence detection unit that detects an occurrence of a transformer substation specific event, a data-compression-instruction output unit, a specific-event-recovery detection unit that detects an end of the specific event, and a data-compression-termination-instruction output unit. An MU and an IED each include a data compression flag setting unit and a data compression unit. The data compression flag setting unit sets a data compression flag to be ON when the MU and the IED receive a data compression instruction, and sets the data compression flag to be OFF when the MU and the IED receive a data compression termination instruction.

1. A transformer substation automation system which couples, via a network, a plurality of control devices that obtain data from each portion of a transformer substation, and which causes the control devices to transmit the data to the network, the transformer substation automation system comprising:
a database that stores determination data for determining whether or not a specific event occurs in the transformer substation; an event-occurrence detection unit that checks the data transmitted from the control devices via the network against the determination data stored in the database to detect an occurrence of the specific event; a first output unit that outputs a data compression instruction for starting a compression of data to the whole transformer substation automation system via the network when the event-occurrence detection unit detects the occurrence of the specific event; a recovery detection unit that checks the data transmitted from the control devices via the network against the determination data stored in the determination database to detect a recovery from the specific event; a second output unit that outputs a termination instruction for terminating the compression of data to the whole transformer substation automation system via the network when the recovery detection unit detects the recovery from the specific event; and a data compression unit which starts the compression of data when receiving the data compression instruction from the first output unit via the network, and which terminates the compression of data when receiving the termination instruction from the second output unit via the network.
