A hybrid tree sensor network for a condition monitoring system to optimise maintenance policy

Wind energy is the leading candidate among renewable energy sources as an alternative to burning fossil fuels. A proper and accurate condition monitoring plan is necessary to ensure the high reliability and availability required by energy production systems. This article proposes a wireless mesh network to implement a widely distributed condition monitoring system for a wind farm. Using different types of sensor, the condition monitoring system evaluates the health state of each turbine. The aim of the work is to propose an architecture that can identify possible incipient failures in the most critical turbine's components. Using this system, it is possible to guarantee continuity of service minimising the unplanned maintenance operation due to hidden failure.
