Abstract

Synchrophasor measurements are an essential tool of modern power systems, and there is increasing interest in their use for studies of distribution network phenomena. However, synchrophasors only describe the fundamental component of the waveforms applied to them, while distribution networks are known to be rich in harmonic content. This paper conducts a brief study based on voltage and current waveforms acquired from a typical domestic electrical supply. It is shown that synchrophasors are lacking in their ability to reconstruct the original waveforms, particularly the current. By estimating harmonics in a manner similar to that of the fundamental, the reconstructed waveforms become closer approximations to the original. It is also shown that harmonic content varies significantly with time. These observations should be factored into the design of emerging distribution network synchrophasor measurement systems.
