Monitoring and its effect on O&M
This chapter outlines the current knowledge in the field of CM for renewable generation systems, primarily based on the author and colleague's experience in the electrical machine and wind industry, and on Coronado et al. (2015). Recently published reliability studies are summarised, and the sub-assemblies of most concern for O&M are identified. This is followed by a description of the state-of-theart in CM, looking at both new and emerging techniques being researched, and industry-developed tools, with a particular focus on the economic benefits of CM. Conclusions are then drawn about current systems challenges and limitations.
