FIELD: physics, computer engineering.SUBSTANCE: invention relates to a merging unit for substation automation. Disclosed is a merging unit (100) for substation automation, which comprises at least one input interface (110a, 110b) for receiving input data (ID) characterising at least one voltage and/or current related to a component of a power system (200), wherein said merging unit (100) comprises timing synchronisation means (156) which comprise an interface to an external synchronisation network operating according to one of the 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 (100) is configured to implement logical nodes (TCTR, TVTR) according to the International Electrotechnical Commission (IEC) 61850-7 standard, and to map information to and/or from at least one of the logical nodes (TCTR, TVTR) to the IEC 61850-9-2 sampled measured values (SMV) communication protocol.EFFECT: increased operational flexibility and reduced complexity for higher level architectures of a substation automation system, and improved power quality monitoring and stability of an electrical distribution grid.10 cl, 5 dwg |
