METHOD AND SYSTEM OF REAL-TIME ESTIMATION OF TRANSMISSION LINE PARAMETERS IN ON-LINE POWER FLOW CALCULATIONS

摘要

A system and method for estimating parameters of transmission lines employingphasor measurement units is provided, wherein measurements are provided fromthephasor measurement units relating to a transmission line. These measurementsarefiltered to remove invalid measurements. Using the remaining validmeasurements,resistance, reactance and grounding admittance are calculated and estimatedandchecked for errors.
