Real-time measurement of power disturbances: Part 2. Implementation and evaluation of the novel complex filter/recursive algorithm

The novel complex filter/recursive algorithm, which are proposed in part 1 of the two-part series, is an improved signal processing technique that can accurately and continuously measure the instantaneous electrical quantities such as the amplitude, phase angle, frequency and power of the fundamental and harmonic components even during power disturbances. This paper, which is part 2 of the series, focuses on the ways to implement the proposed method for real-time applications. Further, the effectiveness and superiority of the proposed method over the well-known Fourier Algorithm (FA) and the Morlet wavelet-based Continuous Wavelet Transform (CWT) are also ascertained in this paper using both simulated and practical power disturbance waveforms.
