There are three acquisition groups in the BERTA Certification application:
The first relates to simulated voltage signals and real-time operation monitoring parameters.
The second relates to analog signals from the actual speed governor and the BERTA algorithm.
The third group collects digital signals from the actual speed governor.
Acquisition Group 1 (ACQ-1)
The first acquisition group collects all voltage signals at the reference frequency (60 Hz in North America). This acquisition allows you to compare the simulated voltage with the V_F0 reference voltage.
These are the six signals collected:
No of overruns = number of overruns.
Computing time = calculation time.
Idle time = idle time.
Time Step = timestep (normally 50 ms),
V_sim = simulated voltage
V_F0 = reference voltage.
Acquisition Group 2 (ACQ-2)
The second acquisition group collects the 20 analog signals from the actual speed governor and from the BERTA algorithm. All these signals are recorded in a file for each new test.
