How big data can lead to lower wind power costs

Logged data from a turbine vs time. Diagnostic models enable advice to be issued well before the turbine generates a warning or an alarm, allowing timely advance planning of appropriate service activities

  • Simplified example of a diagnostic model, in this case relating to hydraulic oil temperature. The red plot is calculated temperature from the model, the green plot actual temperature. The upper graph shows the rise of oil temperature leading to turbine stop. The lower curve shows how the diagnostic model detects an anomaly before the temperature limit is exceeded
  • Siemens broke ground on a new diagnostics centre for wind turbines in January 2014 at the company’s wind service headquarters in Brande, Denmark.
