基于有限元的海上风机雷电电磁暂态分析
Lightning Electromagnetic Transient Analysis of Offshore Wind Turbine Based on Finite Element Method
摘要
Abstract
The inside of the wind turbine,in case of lightning,will generate strong electromagnetic interference and affect normal operation of the wind turbine.For studying the electromagnetic effect on the electronic equipment of the offshore wind turbine in case of lightning on the nacelle of the offshore wind turbine,a finite element model of the na-celle,tower and grounding body of the offshore wind turbine is set up,the simulation experiment of electromagnetic transient distribution in the case of lightning on the offshore wind turbine cabin is performed and the corresponding lightning protection measures are proposed.The simulation results show that,in case of lightning on the nacelle,the magnetic induction intensity on the top of the tower is the largest,which can be up to 3.24×10-4 T,and decreases grad-ually along the tower wall to the periphery of the tower.The magnetic induction intensity increases with the increase of the seawater depths in the environment where the grounding body is located.Compared with the electromagnetic field distribution of the first and second lightning of the wind turbine in the marine environment,the magnetic field amplitude generated by the second lightning current is smaller than that of the first one,which is about 1/4 of that of the first one,but its fluctuation is more violent.关键词
