Simulation model of micro-grid including a direct-drive wind power generation, two sets of power-controlled distributed generations (DGs) and a three-phase fault module was investigated in Matlab/simulink. Based on the constructed model, the operating process switched from island mode to grid-connected mode was simulated and the voltage variance signal was detected with Daubechies(Db) wavelet. The...
Lifting wavelet is a useful method to analyze the abrupt signal because lifting wavelet can simultaneously show the local characteristic of time domain signal and frequency domain signal. The dynamic power quality disturbance in modern power supply can usually engender the fault signal such as voltage sag, voltage swell and voltage interruption. Lifting wavelet and Fourier transform are used respectively...
