Description

technical field [0001] The invention relates to the technical field of voltage sag, and in particular to a method, device and equipment for identifying multiple disturbance sources of voltage sag based on PSO optimization width learning. Background technique [0002] Voltage sag refers to the phenomenon that the effective value of the supply voltage suddenly drops and then rises and recovers in a short period of time. At present, the identification method of voltage sag multiple interference sources is generally used to identify voltage sag, but the identification methods of voltage sag multiple interference sources mainly include: Two parts: feature extraction and source identification, source identification and feature extraction are separated, which increases the identification time to a certain extent. And feature extraction generally uses Fourier transform (FT), Wavelet Transform (WT), Hilbert-Huang Transform (HHT), S transform, etc. to extract the data. To a certain e...
