Abstract
- Fast and accurate synchrophasor measurements are of crucial importance for monitoring next-generation power distribution networks. While most of the Phasor Measurement Units (PMUs) used nowadays in transmission networks rely on static phasor models, more sophisticated models and stricter accuracy requirements are necessary to track amplitude, phase and frequency changes of power waveforms in strongly dynamic scenarios (i.e. in the presence of a variable number of generators and loads). In this paper a novel DFT-based approach is used to estimate not only amplitude and phase of the collected power waveforms, but also their frequency and rate of change of frequency (ROCOF). The performances of the proposed method are evaluated through multiple simulations in different operating conditions, as recommended in the Standard IEEE C37.118.1-2011. [ABSTRACT FROM PUBLISHER]
