Machine Learning helps make complex systems more efficient. By applying advanced Machine Learning techniques such as Cognitive Fingerprinting™, wind project operators can utilize these tools to learn from collected data, detect regular patterns, and optimize their own operations.
Research has demonstrated the value of Machine Learning in delivering next generation analytics to improve safety, performance, and reliability in today’s modern wind turbines.
5. Cost of Gearbox Failures
u Romax Study estimated cost of
planetary bearing failures
>350k[1]
u In 2014 Siemens wrote down
€223M to replace bearings in
fleet <2 yrs. old[2].
u Controlling wind turbines with
data-driven software could,
models show, increase energy
production by at least 10% and
gains of 14-16% are possible[3]
u The average gearbox failure rate
over 10 years is estimated at
5%[4].

14. Category Key Features
Business Intelligence (BI)
• Centralizedanalysis
• Uniform data collection
• Average visualizations
Rules Based Modeling
• Fixed rules must account for all types of transactions in all
types of conditions; lead to rule proliferation and
management challenges
• May be good measures for some simple situations, but
average (or even sub-par) measures for others
Statistical Analysis
• Identifies deviations from “normal”
• More a platform for model building and data scientists
than an alert generating solution
• Not automated to account for changing conditions
Physics Based Modeling
• Asset-type specific
• Model building Is a very hands-on process involving
laboratory experiments
• Domain experts apply these physical models universally to
assets
