Abstract

Optimal asset management strategies for wind turbine blades help to reduce their operation and maintenance costs, and ensure their reliability and safety. Structural health monitoring (SHM) can determine the health state of wind turbine blades through implementing damage identification strategies. The main load-bearing structure spar of the wind turbine blade is inside the structure, and hence difficult to inspect. Advanced SHM techniques, such as guided wave monitoring, can be used to monitor the development of cracks in real-time and provide an early indication of their existence. This paper presents a risk-based maintenance model based on the state information provided by SHM. The model is based on Petri nets, and describes the blade degradation and guided wave monitoring processes, inspection and maintenance works. Fatigue test data of composite components is processed to provide input for the model. The reliability of guided wave monitoring is also assessed. The proposed model is able to predict the condition state and expected number of repairs of composite components for wind turbine blades, which can potentially help in making informed asset management decisions during wind turbine blade operation.
