An enhanced version of the Morlet wavelet-based two-point FIR (MW-FIR) method is proposed to improve immunity against disturbing signals. The estimators are tested and compared with other methods, showing significant improvements in most circumstances, particularly under challenging tests.
Recently, a new approach called Morlet wavelet-based two-point FIR (MW-FIR) is proposed for the phasor estimation. Although the approach shows several advantages, it is still not fully compliant with all standard requirements. In this case, the paper proposes the enhanced version of the MW-FIR method to improve immunity against disturbing signals. The estimators are tested under IEC/IEEE 60255-118-1, and compared with other state-of-the-art methods. Results show that the enhanced P-class estimator improves almost all circumstances while the M-class one improves under the most challenging tests, out-of-band interference (OOBI), by around 10% and 20%. Additionally, the enhanced algorithms can reach the best performance without iterations.
