Novel Application of Detrended Fluctuation Analysis for State Estimation Using Synchrophasor Measurements
A synchrophasor or phasor measurement unit is a state-of-the art GPS enabled device that records highly accurate time-stamped power system measurements up to 50 times a second. The installation of such devices on the National Grid power transmission system provides far greater observability of the steady and dynamic states of the system. This paper applies detrended fluctuation analysis to National Grid synchrophasor data to more accurately differentiate between steady state behaviour and dynamic events as they occur on the system. The paper reports on National Grid sponsored industry led research performed through the EPSRC funded Brunel University Engineering Doctorate Scheme.
