| Sumario: | The present project proposes a wind turbine model for studies about its effects with reference to lightning strikes. For this, a meticulous compilation of high frequency models of each element of a conventional wind turbine has been carri ed out in order to select the most suitable ones. Subsequently, these models have been introduced in the ATPDraw software to perform the relevant simulations. In parallel, due to the absence of models about the power converter in the available literature, we have tried to model it and obtain an equivalent circuit that could reflect its behaviour in lightning tests . To do this, a series of experiments were carried out using a pulse generator and real equipment to obtain tangible information about its behavio ur and, then , some t ests were carried out with different models u ntil finding one that offered the adequate operation . Finally, all previously evaluated models are introduced into the ATPDraw forming a wind turbine, and an impulse similar to that of a stan dard lightning is applied . In this way, it is possible to study which is the overall behaviour of the whole system and specifically , about each element presented to obtain the final conclusions. As a whole, it can be said that a relatively simple system is obtained that offers a performance very similar to the reality one |
