Emergency Pitch Systems that depend on a basic battery set up for its emergency power unit (EPU) are vulnerable to a variety of technical and logistical problems:
Business Challenges of Battery Based Emergency Pitch Systems also include:
The solution? Ultracapacitors.
Ultracapacitors are more reliable and better handle the extreme temperatures, whether it be extreme heat of Texas or the extreme cold of the far north. They have these characteristics while not relying on an internal chemical reaction to deliver the power. Life expectancy is also 3 to 4 times the expectancy of a battery! You should never have to replace the ultracapacitor retro again.
Utilizing ultracapacitors has shown to reduce pitch system maintenance efforts and increase uptime. Using batteries for backup power presents several issues. These include intermittent pitch faults due to inefficient charge/discharge capabilities, unexpected failures, shorter life span, and increased turbine downtime to address these issues. This also eliminates those pesky GE EPU fault conditions caused by a faulty battery charger or battery.
Using batteries ultimately affect the overall operation of the pitch system and the turbine. Switching to ultracapacitors eliminates the regular maintenance and replacement necessary to maintain battery backup power. Switching to ultracapacitors is painless and do not need additional software or extra costly hardware to make the switch. UpTower can offer you the entire package with install for one price!
Safety in the industry isn't just a priority, its a necessity-lives depend on it.
Alternative energy storage technology like ultracapacitors to replace batteries is worth serious consideration knowing each battery voltage fault requires a technician to troubleshoot or replace batteries.
With a more reliable backup energy storage for the pitch systems sites can eliminate normal climb risks including:
