3.1.3.1 Reporting the measured values and the changes
It is usual for the SCADA systems that they sample the measured and calculated values in
regular time periods and additionally they receive the changed values as reports at the
moment when any significant change is detec
ted in the primary system. The “Line
measurement” function block is able to perform such reporting for the SCADA system.
3.1.3.2 Operation of the line measurement function block
The inputs of the line measurement function are
•
the Fourier components and true RMS values of the measured voltages and
currents
•
frequency measurement
•
parameters.
The outputs of the line measurement function are
• displayed measured values
• reports to the SCADA system.
NOTE: the sca ling values are entered as parameter setting for the “Voltage transformer
input” function block and for the “Current transformer input” function block.
3.1.3.3 Measured values
The measured values of the line measurement function depend on the hardware
configuration. As an example, table shows the list of the measured values available in a
configuration for solidly grounded networks.
