Vibration Signals and Condition Monitoring for Wind Turbines

Online Nonintrusive Condition Monitoring and Fault Detection for Wind Turbines

Wheelset Condition Monitoring based on pass-by vibration signals

Apart from regular wheel wear such as decreasing wheel diameters and reduced flange thicknesses and heights, wheel flats (WF) and oval wheels (or OOR, Out-Of-Roundness) are the most common wheelset problems for railway vehicles. Within the FP7 Research Project “Saferail”, APT has developed an innovative wheelset monitoring system so-called “Wheel flat and Out of Roundness Monitoring (WORM) syst...

Developing RCM strategy for wind turbines utilizing e-condition monitoring

Renewable energy sources such as wind energy are available without any limitations. In order to extract this energy efficiency, the reliability of such technologies is critical if pay back periods and power generation requirements are to be met. Due to recent developments in the field of wind engineering and in particular the expansion of installed capacity around the world, the need for reliab...

Quantification of Condition Monitoring Benefit for Offshore Wind Turbines

Condition monitoring (CM) systems are increasingly installed in wind turbines with the goal of providing component-specific information to wind farm operators, theoretically increasing equipment availability via maintenance and operating actions based on this information. In the offshore case, economic benefits of CM systems are often assumed to be substantial, as compared with experience of on...
