On-line parametric estimation of damped multiple frequency oscillations

Undesirable harmonic pollution is currently a reality in many electric power systems. Damped transients generated by the growing use of electronically controlled devices are an important source of harmonic distortion of voltage and current waveforms. Accurate real-time estimation of harmonics parameters during the on-line operation of some electric power system is thus an active and pertinent challenging research issue. In this paper a novel...
