Ship Power Quality Detection based on Improved Hilbert-Huang Transform
2012
Journal of Computers
Hilbert-Huang Transform (HHT) and its improved method are introduced to detect and analyze power quality in ship power system for the first time, in this paper. The HHT method is used to detect surge current, voltage sag and swell, voltage interruption, etc. of the ship power system. By means of Hilbert-Huang transform, Beginning time, ending time, time-frequency, timeamplitude of the disturbance signal can be obtained accurately. Because the fundamental energy is bigger than other single
