Cut O&M Costs with Ultracapacitors (Supercapacitors) for Wind Turbine Emergency Pitch Control Systems (ARTICLE)

| Maxwell Technologies

More wind farms leave behind traditional approaches as emerging technologies improve operations and wind turbine performance.

This is the case for wind turbines with battery-based emergency pitch control systems. In this Windpower Engineering & Development article, Josh Hitt, senior product line manager at Maxwell Technologies, covers why wind farms are opting in for ultracapacitor-based energy storage for pitch control.

"Ultracapacitors are a reliable energy storage option that has resolved many of the typical pain points with battery-based systems,” writes Hitt. "Ultracapacitors, also called supercapacitors, are high-powered energy storage devices that store charge electrostatically. In contrast, lead-acid batteries operate electrochemically, with inherent disadvantages due to the nature of their chemical process. As a result, ultracapacitors offer much greater efficiency and reliability in emergency pitch controls and require no scheduled maintenance for 10 years or longer.”
