1. A remote communication system, the system comprising:
- a digital protection relay configured to store and maintain fault indices for identifying a predetermined number of faults that have occurred, fault time tags corresponding to the fault indices and fault data corresponding to the fault indices; and
a remote monitoring system configured to set a fault index, fault time tag, fault data block size, and fault data block index for specifying a fault data block of one or more fault data blocks of the fault data to be communicated, and to request the fault data block from the digital protection relay,wherein the digital protection relay transmits the specified fault data block to the remote monitoring system based on the fault index, fault time tag, fault data block size, and fault data block index received from the remote monitoring system.

Abstract
Disclosed is a remote communication system and method. A remote communication system includes a digital protection relay and a remote monitoring system. The digital protection relay stores and maintains fault indices for identifying a predetermined number of faults that have occurred, fault time tags corresponding to the fault indices and fault data corresponding to the fault indices. The remote monitoring system sets a fault index, a fault time tag, a fault data block size to be communicated at a time and a fault data block index for specifying a fault data block to be communicated, and requests the digital protection relay of a fault data block.

6. A method of performing remote communication between a digital protection relay and a remote monitoring system, the method comprising:
-
storing fault indices for identifying a predetermined number of faults that have occurred, fault time tags corresponding to the fault indices, and fault data corresponding to the fault indices; receiving a request for specific fault data from the remote monitoring system, the request including a fault index, fault time tag, fault data block size, and fault data block index corresponding to a fault data block of one or more fault data blocks of the specific fault data; and transmitting the corresponding fault data block from among the stored fault data to the remote monitoring system based on the requested fault index, fault time tag, fault data block size, and fault data block index. - View Dependent Claims (7, 8, 9)
