Lightning Overvoltage and Protection Measures for Offshore Wind Turbines
摘要
Abstract
The complex marine environment makes the transient overvoltage caused by lightning strike on wind turbine blades more prominent,which puts higher requirements for the reliability and effectiveness of lightning protection system.The current research on lightning protection only focuses on the first light-ning strike,and only observes the potential rise of the blade,tower and grounding device,but ignores the potential rise of the electrical part in the engine room,especially on both sides of the engine room trans-former.By building a lightning strike transient integration model of the offshore wind turbine in the ATP-EMTP software,the author analyzes the transient process of the engine room transformer after the blades are subject to the second lightning strike,as well as the lightning protection effect after connecting SPD and arrester,providing a basis for lightning protection and insulation coordination of the offshore wind turbine.关键词
