Abstract

Measurement delay for state estimation outliers adverse consequences, affecting the right conclusion. In this paper, the possible measurement delay is given through the analysis of SCADA data acquisition and transmission process. Based on the verification platform of dispatching automation system, the measurement delay case is constructed. The influence of measurement delay on state estimation is analyzed quantitatively. A method based on unified time scalar in SCADA system is proposed. The influence of time error caused by various reasons on state estimation is solved.
