6.1 Measured Value Acquisition and Processing

45Digital Fault Recorder, SIMEAS R-PMU, Manual

E50417-H1076-C360-A5, Release 10.2012

Resampling

The constantly sampled measuring signal (192 sample values per nominal period) will be distrib-

uted based on the reference frequency onto 128 values per measured signal period.

Fast Fourier transformation

Fast Fourier transformation is used to create the phasors of the basic oscillation. All other values

(e. g. effective power, reactive power, positive sequence system, negative sequence system)

are calculated from the basic oscillation. The measured values are also used to derive the trigger

conditions for the Transient Phasor Recorder (TPR).
