A detailed analysis of the recoded failure data of the wind turbines in Zafarana windfarm namely Site-3 has been introduced. The failure cost consequences of one ofthe main components of the wind turbine have been introduced for cost analysis andmaintenance planning.The effect of variation of the capacity factor and the down time on failure costconsequences is introduced. The down time has a significant effect on the failurecost consequences of wind turbine components. The failure recoded data have beenillustrated for one year for the same site for different wind turbine components whilethe capacity factor has only effect on gearbox and blade failure cost.For failure rate and reliability analysis, the Weibull distribution has been introduced,the modified maximum likelihood method has been used to evaluate the Weibulldistribution parameters. The failure rate and reliability have been studied for differentwind turbine components. The initial failure rate after one month (720 h) was 0.0026while the failure rate was 0.0084 at the end of the year (8760h) for the generatorcritical components. |
