Simulation of sampled values
SAM600-VT and SAM600-CT modules support a simulation mode.
An individual SAM600 module or all SAM600-VT and SAM600-CT modules of a
SAM600 system can be set to simulation mode by selecting the SAM600
Command
Simulation Mode
in the PCM600 navigation tree on the appropriate
level.
The simulation mode is not persistent and will revert back to its
default value (Simulation Mode off) upon the next restart of a
SAM600 module.
The simulated values with the quality information
Substituted
will
be processed as valid values by any 61850-9-2 subscriber. This has
to be considered for systems in operation.
Sine waves with nominal values and frequency will substitute the measured values.
The frequency of the generated sine wave is according to the configuration
parameter
Power system frequency.
The resulting sine wave nominal amplitude is scaled according to the configuration
parameter
Transducer value on primary
. Phase A has a zero-crossing at the full
second.
Simulated values are merged according to the same rules as measured values (see
conditions in
). The values are provided on the IEC61850 access points.
The detail quality information of the samples in the IEC/UCA 61850-9-2LE stream
for simulated data is set to

Digital inputs
SAM600 modules have four digital input channels. These digital inputs have pre-
assigned process supervision functionality as described in

The voltage level of the high potential (channel is
active
) for all channels can be set
to different values (24V, 48V, 110V, 125V, 220V DC). The voltage level of the
low potential (channel is
off
) is 0V.
