This study describes a synchrophasor estimation method and its hardware implementation applicable at the distribution level of the power system, under steady‐state or dynamic conditions. The method proposed is based on the discrete Fourier transform and uses the Savitzky–Golay filter in the frequency estimation process. The main goal of this study is to present the signal processing algorithm for phasor estimation and some important issues regarding its implementation in real‐time systems. The performance of the micro‐phasor measurement unit ( μ ‐PMU) is validated using a waveform generator and real‐time power system simulator.
