Abstract
Official abstract text for this publication.
The adaptive fault location method for power system networks utilizes phasor measurement units (PMUs) disposed at disparate locations to obtain synchronized phasor measurements. Three different sets of pre-fault voltage and current phasor measurements are obtained at both terminals of the line under test. The three sets of local PMU measurements at each terminal are used for online calculation of a corresponding system's Thevenin equivalent (TE). This representation of the power system pre-fault network is a reduced two-terminal equivalent. Using the method of multiple measurements with linear regression (MMLR), the three sets of PMU measurements are also employed for online calculation of the transmission line parameters (series resistance, series reactance and shunt susceptance). Online determination of the TEs and line parameters can enhance fault location accuracy by avoiding possible mismatch with the actual parameters due to system loading and other environmental conditions.
First claim
Opening claim text (preview).
We claim: 1 . A method for adaptive fault location in a power system network, comprising the steps of: acquiring a plurality of independent sets of phasor measurement unit (PMU) pre-fault measurements from a first terminal and a second terminal of a line in a power system network; acquiring at least one set of PMU post-fault measurements from the first terminal and from the second terminal; determining the power system network Thevenin equivalents at the first terminal and a…
