Research of Lightning Protection Technology for Variable Speed Direct Drive SRG Wind Power System

Abstract:By using the research results on lightning protection of wind power units, and the lightning protection standards for the relevant industry, the formation, failure mechanism and the damage form of lightning is analyzed. Combined with the feature of SRG wind power system, the lightning protection area is divided; According to the principles that should be followed to design the lightning protection system of wind power units, the external lightning protection is combined with internal lightning protection, and the lightning protection measures of SRG wind power system are proposed. For lightning protection of SRG wind power system in the engineering practice, certain reference is provided.
