Abstract
A merging unit for substation automation includes at least one input interface for receiving input data characterizing at least one voltage and/or current related to a component of a power system, and a timing synchronization mechanism which includes an interface to an external synchronization network operating according to one of Inter Range Instrumentation Group, IRIG, -B standard, the 1PPS standard and the Institute of Electrical and the Electronics Engineers, IEEE, 1588 standard. The merging unit is configured to implement logical nodes according to the International Electrotechnical Commission, IEC, 61850-7 standard. The merging unit is configured to map information to and/or from at least one of the logical nodes; to the IEC 61850-9-2 sampled measured values, SMV, communication protocol.
