This chapter has described the development of SCADA and CMS in WTs showing that the former is cheap and gives breadth of coverage, whereas the latter is more costly but gives depth of diagnosis. The chapter has also shown successful examples of SCADA and CMS monitoring giving reliable detection, diagnosis and prognosis of failure modes in the most important sub-assemblies on real WTs in the field and on a WTCMTR. Good potential for fault detection with significant warning is possible with both monitoring systems, but there is clear evidence that integrating SCADA and CMS data would increase confidence in their indications.
