What wind-farm information can help identify availability issues?
What will be an ideal response?
SCADA information and service reports may be used to determine issues that lead to reduced turbine and farm availability. For example, if a wind turbine changes from “On-line” to “Shut down” mode the SCADA status log will list information such as date, time, and new status. If status change is due to the occurrence of a fault, the log also lists fault information.
