— When doing parameter estimation, ESPRIT is an often used algorithm. As input, ESPRIT needs the eigenvectors of the signal subspace. These can be generated by an eigenvalue decomposition or by subspace tracking algorithms. In this paper, we demonstrate, that subspace tracking is superior not only regarding computational complexity but also regarding(More)
A power system grid can be modeled as a circuit of various RLC-meshes. In case of a switching event, some of those RLC-meshes are excited. These will produce additional frequency components within the power signal. In this paper, a concept which uses a priori information of these meshes for event-characterization is presented. Frequency estimations done(More)
