The implementation of the IEC61850-9-2 standard in substation automation systems requires the use of merging units for elimination of several multiple wire connections running from the switchyard to the microprocessor relays located in the control room. The conventional merging unit model collects ...
(57) ABSTRACT A merging unit, for example for Substation automation, including 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...
