Abstract :
In this paper the lifetime of the power semiconductors in the rotor side converter of a wind turbine with Doubly Fed Induction Generator (DFIG) concerning their power cycle capability is examined. Based on the offshore wind velocity data of one year (FINO station), the corresponding temperature cycles of the power semiconductors in the converter are simulated for a 2 MW DFIG. The simulation is based on a partial load control strategy and an adequate selection of the power module. With three different cycles-to-failure statistics, the lifetime consumption of one year is estimated.
