The first wireless wind turbine blade sensor for automatic, real-time condition-based monitoring

Periodic Reporting for period 1 - EOLOGIX (The first wireless wind turbine blade sensor for automatic, real-time condition-based monitoring)

Reporting period: 2019-09-01 to 2020-08-31

Maintenance costs are one of the largest problems in the wind energy market, adding to up to 40% of total wind turbine costs. Blades take the lion’s share of this, with 20-30% of all maintenance costs. Our solution is an on-blade sensor system to combine 3 features: blade crack detection, pitch angle measurements and blade icing detection. Monitoring all these features will save wind turbine owners up to €2.9 M across the turbine lifetime.
Generating more green energy from both new and retrofitted wind turbines is the main benefit for society from our product. Increased production and continuous condition monitoring contribute to more CO2 neutral energy and a safe environment.
"Since the beginning of the project, Eologix has integrated new components into the main platform component, the ""sensor"" which is mounted to the blade surface at various locations. Software has been developed for both sensor and receiver / base station, data have been simulated and a dedicated test stand has been developed, built and brought into operation. 300 devices have been manufactured to equip a minimum of 5 prototype systems at both new and existing customers. The Eologix homepage has been redesigned to be prepared for the official product launch in Q4/2020."
The first prototype systems will go into operation by the end September 2020. Early evaluations already show that a data quality unknown so far can be achieved by measuring the vibrational behaviour of the blade at multiple, dedicated points. This will even allow for more applications in production optimazation than assumed before.
I would add further info about the state of art (comparison between the state of art explained within the proposal and the current existing)
Current systems rely on either sensors mounted in the blade root (inside the turbine) and measure - by design - on one or two points per blade quite close to the root. Other available systems require the placement of optical fibers which do not offer long-term stability and need to be routed through the entire blade and therefore require high mounting effort.
Our new product can be easily mounted as a retrofit solution but also be mounted to new turbines a product option. Wireless data transmission makes physical wiring inside the blade obsolete. Also, the biggest signals to pick up in terms of vibrations and motion are located at the blade tip where no existing system can be mounted.
