Identification of Harmonic Sources in Electrical Power Systems using State Estimation with measurement error

Luis Alberto Hernández Armenta, David Romero Romero, Jaime Robles García

Abstract


In this article it is shown that the Total Harmonic Distortion (THD) of the current is a reliable index to identify the location of harmonic sources in a Power System. It is proved that the harmonic estimators fail to identify harmonic sources measurement errors. A 14 node system with two sources of harmonic solved by two methods is tested.
