Method and system for current differential protection

A method, comprising:

• providing one of a ring topology or a mesh topology comprising a local terminal and at least two remote terminals, wherein the local terminal is configured to be communicatively coupled directly or indirectly with the at least two remote terminals via at least three communication links;
• determining at least one of the at least three communication links as virtually disconnected such that one of the ring topology or the mesh topology of the local terminal and the at least two remote terminals is configured to be converted to a daisy chain topology;
• synchronizing time of the local terminal with at least one of the at least two remote terminals when the local terminal and the at least two remote terminals are configured in the daisy chain topology;
• detecting a fault in at least one communication link of the at least three communication links;
• receiving an indication for the fault in the at least one communication link;
• defining the determined virtually disconnected communication link as an operational link, when the at least one faulty communication link is different from the determined virtually disconnected communication link;
• and
• defining the at least one communication link as the at least one faulty communication link based on the received indication.

A non-transitory computer-readable medium comprising computer-readable instructions of a computer program that, when executed by a processor, cause the processor to perform a method, the method comprising:

• providing one of a ring topology or a mesh topology comprising a local terminal and at least two remote terminals, wherein the local terminal is configured to be communicatively coupled directly or indirectly with the at least two remote terminals via at least three communication links;
• determining at least one of the at least three communication links as virtually disconnected such that one of the ring topology or the mesh topology of the local terminal and the at least two remote terminals is configured to be converted to a daisy chain topology;
• synchronizing time of the local terminal with at least one of the at least two remote terminals when the local terminal and the at least two remote terminals are configured in the daisy chain topology;
• detecting a fault in at least one communication link of the at least three communication links;
• receiving an indication for the fault in the at least one communication link;
• defining the determined virtually disconnected communication link as an operational link, when the at least one faulty communication link is different from the determined virtually disconnected communication link;
• and
• defining the at least one communication link as the at least one faulty communication link based on the received indication.
