This chapter has presented the essential reliability mathematics necessary to understand the data collected from WTs and wind farms, and presented in this book. It shows that simple methods can be used to extract essential information and the overall results that can be obtained. However, care must be taken in manipulating the data to ensure that interpretations are sound.
