A generic architecture for robust automatic detection and suppression of sub-harmonics

Abstract

Sub-harmonic phenomena become a critical issue as properties of the power grid change. In this paper we propose a generic architecture to detect and suppress these sub-harmonics automatically in a robust way. Therefore different algorithms to analyse the signals from the power grid, like wavelet- and prony analysis, are used and extended to rate and incorporate signal quality. The results of these algorithms are dynamically fused using according to their trustworthiness in order to achieve a detection as robust as possible. Afterwards the intervention needed to suppress a detected sub-harmonic is determined and applied by remote load management in our case. First experimental results show the validity of this trustworthiness-based architecture. © 2013 Lecture Notes in Informatics (LNI), Proceedings - Series of the Gesellschaft fur Informatik (GI).
