Matrix pencil: A novel approach for fast shunt compensated controlled switching

In this paper a novel and efficient approach is presented for power system switching transient analysis: The so-called Matrix Pencil Method MP, is based upon a modal decomposition of exponentially modulated sinusoids, formulated as a generalized eigen-value problem. In this paper we are interested in shunt compensated line transient voltages during auto re-closing operations. The MP method has readily proved it´s efficiency in many areas (speech pattern recognition, aircraft, signal processing etc). Moreover, for such class of signals it shows better performance than many improved versions of the Prony´s method such us Tufts and Kumaresan polynomial one. Many validation tests were carried out onto typical transient signals issued from EMTP/ATP simulations for different network configurations and show very satisfactory results.
