Infographic: The Advantages of Ultracapacitor Energy Storage for Wind Turbine Emergency Pitch Backup Systems

| Yayoi Suzuki, Sr. Global Marketing Communications Manager

Did you know that ultracapacitors have operated for the past two decades in wind turbines for reliable emergency pitch control?

Ultracapacitors, also called supercapacitors, are high power energy storage devices that provide rapid power to pitch a turbine’s blades to a safe position during an emergency shut-down situation, such as when there is grid power loss or high wind speeds that force a shut-down of the turbine.

Many wind farms experience downtime when the pitch system’s lead-acid batteries require maintenance or replacements. Almost 20 years ago, Maxwell deployed its proprietary ultracapacitor solutions for emergency pitch control to support wind farms’ efforts to minimize maintenance efforts, increase generation uptime and improve site operations.

The below infographic provides those new to ultracapacitor technology with a summary of its top benefits for the critical pitch control application.
