in the bottom of each function block. For each instance, there are three separate BINARYREPORT
blocks capable of reporting up to 24 Binary signals (8 Binary signals in each BINARYREPORT block).
These binary signals can be for example dis-connector or breaker position indications or internal/
external protection alarm signals.

Operation principle

The Phasor Measurement Unit (PMU) features three main functional principles:
• To measure the power system related AC quantities (voltage, current) and to calculate the
phasor representation of these quantities.
• To synchronize the calculated phasors with the UTC by time-tagging, in order to make
synchrophasors (time is reference).
• To publish all phasor-related data by means of TCP/IP or UDP/IP, following the standard IEEE
C37.118 protocol.
