Evaluation of the Modified Covariance Method Performance with Cleaning Characteristic Harmonic Digital Filter in Protection Relay
Under harsh transient situations, contemporary protection relays necessitate the accurate and swift estimation of phasors. The prior CCHDF filter was limited by DFT techniques and utilized the Biunivocal Frequency Relationship of Phasors (BFRP). The Modified Covariance Method (MCM) is a sophisticated autoregressive spe...
