Wherein: Tt - Number of hours per year, 8760 (h) 

Tcum - cumulated downtime (h) 

Ts - down time under non-operating wind conditions, down time (h), namely, 

V<Vin (cut-in wind speed m/s) and V>Vout: (cut-out wind speed m/s) 

Tpm - scheduled maintenance time (h) 

Tcm - non-scheduled maintenance time, namely, downtime due to failure of wind power generating unit (h). 

Tp - down time due to mis-operation of the use and maintenance personnel (h) 

 

 Page 25 of 35
