Abstract
Wind energy is the leading candidate between the renewable energy sources as alternative to burning fossil fuels. A proper and accurate condition monitoring plan is mandatory to ensure high reliability and availability required by energy production systems. This paper 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 able to identify possible incipient failures in the most critical turbine’s components. Using this system, it is possible to guarantee continuity of service minimizing the unplanned maintenance operation due to hidden failure.
