intermittent and volatility of wind energy make the power quality of power systems very complicated when wind power is connected to the grid.Therefore
in view of the transient power quality problem in the operation of wind power grid-connection in this paper
a kind of a new method based on db4 wavelet transform and RMS method is proposed to detect and identify transient power quality disturbance and is verified by detailed theoretical analysis and Matlab simulation.It is shown by the study result that the method can effectively detect and identify transient power quality disturbances and provide a practical and feasible method for detecting and identifying transient power quality disturbances of power systems during grid-connected operation.
