Early Fault Identification of 35 kV Photovoltaic Collector Cable Based on DWT and SVM Methods
Due to the influence of ozone,ultraviolet radiation,violent temperature change,chemical erosion,photovoltaic collector cables are easy to short circuit,bringing serious harm and loss to power generation.This paper studies an early fault identification method of 35 kV photovoltaic collector cable based on DWT and SVM methods which facilitates detec-tion of the latent fault lines in early stage of fault occurrence.A PSCAD simulation verifies the accuracy of this method.
