ONYX InSight, provider of predictive maintenance to the wind industry, and lubricants expert Castrol have embarked on a multi-phase study designed to uncover the potential of combining oil and vibration data on the accuracy of wind turbine health monitoring.
Advancing predictive maintenance
With the objective to bring the most innovative and advanced predictive maintenance solution to the wind industry market, ONYX InSight and Castrol have completed laboratory testing to measure the effectiveness of sensors to the changing conditions of oil in a simulated wind turbine environment. The tests were carried out using a range of oil sensor technologies, with each sensor type tested in multiple oils from three separate vendors to ensure comprehensive results.
Refining a condition monitoring system
The second phase is now in progress and has seen a rigorous program of oil sensor installations in a commercial wind farm. Data from the field shows excellent correlation between oil sensor and vibration condition monitoring system (CMS) outputs relating to a developing gearbox bearing failure – giving operators even more confidence in the detection algorithm. The trials are helping ONYX InSight and Castrol refine new approaches for an advanced, integrated CMS by combining data from oil condition, vibration sensors and supervisory control and data acquisition (SCADA) systems.
Increasing efficiencies to help reduce levelized energy costs
The pioneering study comes in response to the industry’s need to increase efficiencies to help lower levelized cost of energy. The businesses believe that combining oil data with vibration data offers significant diagnostic advantages that improve maintenance planning across a turbine or fleet when deployed together with machine learning and engineering expertise.
“Current predictive maintenance solutions can already offer significant O&M cost-savings. By adding an additional data stream through combining oil and vibration data, accuracy increases. This allows our customers to generate even higher cost savings,” said Bruce Hall, CEO, ONYX InSight. “As wind farms find their profits increasingly squeezed in the post-subsidy market, it is vital to enable O&M teams to drive maximum operational efficiencies using the latest technology. To continue to innovate and improve predictive maintenance best practice, we need to understand how oil and vibration data can be combined to provide the most accurate insights to enable us to best support our customers’ O&M teams.”
Phil Booker, international application engineer, Castrol, added, “As we work towards a more sustainable future, an important part of our strategy is to ensure that renewable energy sources, such as wind power, can achieve maximum efficiency and performance. We have been at the forefront of supplying best-in-class carbon neutral lubricants to extend wind turbine lifecycles. Now we are working with ONYX InSight to ensure that O&M teams have the knowledge they need to help propel growth in wind energy.”
The study comes as ONYX InSight prepares to launch the first in a series of digitalization reports, which incorporates key findings from the combined oil sensor study along with additional research, to help companies rationalize the volume of data in the wind industry to help unlock the benefits of digitalization. The white paper will be available to download at onyxinsight.com next month.
