The present paper presents the different numerical tools used for lightning protection analysis. Initially the risk assessment considering attachment point distribution and location of vulnerable points on the wind turbine will be discussed, where also the term Lightning Protection Coordination (LPC) is introduced. When these two tools have been used to place air terminations on blades and defining the necessary insulation levels of interior parts, the voltage and current distribution along the blade structure can be calculated. This will put restrictions on the blade design, and define locations and requirements to insulation levels, equipotential bondings, indirect effects protection etc. Finally the lightning current arrives to the nacelle, where the principles of modelling magnetic fields, induced voltages, required shielding of panels etc. will be discussed.
