An optimal procedure for placing sensors and estimating the locations of harmonic sources in power systems

Abstract

The problem of where best to take measurements to estimate the locations of harmonic sources in power systems is addressed. Sensitivity analysis and the minimum variance criterion are utilized to solve this problem. The underdetermined case dealing with a few measurements in a large system is analyzed. Three examples are provided to prove that while the optimal sensor placement problem does not necessarily possess a sequential solution, the sequential solution yields a very good approximation solution.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
