Superposition Power Quality Disturbance Identification System Design Based On Linux Multithreading
Isolation and identification of problems for hybrid power quality disturbances, Presents a Ensemble Empirical Mode Decomposition(EEMD) method. First separation added white Gaussian noise mixed power quality disturbance signal . Secondly separated several single disturbance do Hlibert transform, Finally, to obtain the instantaneous frequency, the amplitude characteristic map Analyzing disturbance Category.Use the embedded Linux system platform, Embedded linux multithreaded programming method achieve Ensemble Empirical Mode Decomposition, Simulation and experimental results show that the system reaches a hybrid power quality disturbances separation and identification purposes.
