Relay dualization apparatus
First Claim
1. A relay dualization apparatus in a substation automation system including at least one or more upper units and at least one or more lower units, the apparatus comprising:
- a plurality of first relays receiving a power data from the lower unit using a predetermined communication method, and transmitting the power data to the upper unit, andreceiving a control command from the upper unit and transmitting the control command to the lower unit; and
a second relay performing communications with the plurality of first relays using the communication method to replace a relay that has generated an error in the plurality of relays;
wherein each of the plurality of first relays comprises a first storage storing the power data, the control command, and event and system algorithm;
wherein the second relay comprises a second storage storing the power data, the control command, the event and the system algorithm communicated by the plurality of first relays, received from the plurality of first relays;
wherein the second storage comprises a plurality of storages to store the data of each of the plurality of first relays, or comprises a storage to divisionally store the data of each of the plurality of first relays;
wherein the second relay performs a real-time or periodical communication with the plurality of first relays and updates the second storage in real-time or periodically; and
wherein the second relay performs to replace the relay that has generated an error in the plurality of relays based on the power data, the control command, the event and system algorithm in the second storage.
