Wind turbine (WT) blades are vulnerable to failure as they are exposed to direct harsh environment, suffering constantly varying loads by wind and cyclic fatigue load due to selfweight, experiencing extreme temperature and humidity changes, erosion and corrosion. As a consequence, blades show high failure rate and share significant downtime, which highlight the significance and essentiality of the research, develop and application of blade Structural Health Monitoring (SHM) techniques. To fulfil reliable SHM of WT blades, much effort has been spent in the past years as reported in literature. But to date, how to realize reliable WT blade SHM is still an open question. The previous reviews enumerate the non-destructive testing techniques that are potentially applicable to blade SHM, but they fail to give a clear suggestion on how to implement reliable SHM of a WT blade. To fill this gap, instead of replicating technique enumeration the present paper is oriented to investigate the pros and cons of existing blade SHM techniques and based on which, a newly developed blade SHM technique that is effective in both damage detection and location is discussed.
