In order to instruct more scientific and effective lightning protection methods, a targeted comprehensive strategy for lightning protection from surface to line to point by synthesizing operating experience, lightning zones map, lightning risk assessment, and treatment technology is proposed based on the practical management demand and differentiation idea of lightning protection. The strategy is applied to the Anhui power grid. Firstly, the characteristics of historical lightning faults are summarized; secondly, the lightning zones maps in the overall province and along transmission lines are plotted to determine regions with strong lightning activities; thirdly, according to the lightning risk assessment and the treatment technology, the risk grades as well as its determination for typical transmission lines are evaluated, and several reform schemes are made with their technology and economy as definitely given. The related results have been applied to the lightning protection work in the Anhui power grid.
