The traditional transient power quality disturbance detection method of doubly-fed wind power grid-connected system directly extracts the feature quantity,but does not denoise the voltage signal,and the detection overhead is high.Through the research on transient power quality disturbance detection of doubly-fed wind power grid-connected system,the voltage signal noise reduction was processed,and the characteristic quantity was extracted,and the transient power quality detection process was designed to realize the transient power quality disturbance detection of doubly-fed wind power grid-connected system.The results show that the detection cost of the proposed method is low and the efficiency is high.
