A complete model of wind turbines for lightning transient analysis
A transient analysis is performed in this paper for the wind turbines (WTs) struck by lightning. The equivalent circuits of blade, moving contact site, tower, and earth-termination system are built, respectively, and a set of analytic formulas are presented to evaluate their circuit parameters. By assembling the equivalent circuits of these separate parts, a complete model is set up for describing the lightning transient behavior of the WTs. Then, the transient responses can be obtained at different locations in the WT on the basis of the numerical solution to the network equations. In order to check the validity of the model, a laboratory experiment has been made on a reduced-scale WT. The model has also been applied to lightning transient analysis of an actual WT with a rated power of 2.5 MW.
