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 employin g phasor measurement units is provided, wherein measurements are provided from the phasor measurement units relating to a transmission line. These measurements are filtered to remove invalid measurements. Using the remaining valid measurements, resistance, reactance and grounding admittance are calculated and estimated and checked for errors.
