HIGHLIGHTS
- who: Detection and colleagues from the College of Energy, Xiamen University, CO , China have published the article: Automatic Expansion of Voltage Signals Using Empirical Mode Decomposition for Voltage Sag Detection, in the Journal: (JOURNAL)
- how: They can decompose the sampled signal into scale coefficients and wavelet coefficients which can be analyzed to determine when the voltage sag starts and ends. To overcome the interference of voltage harmonic and achieve rapid voltage sag detection this paper proposes a tailored EMD-based adaptive real-time voltage signal expansion method for real-time voltage sag detection.
