REIVAX performs life extension upgrade on UNITROL F Static Excitation systems
Learn how Reivax designed, manufactured, installed and commissioned four (4) front-end control upgrades on aging ABB UNITROL F excitation systems at the Fort Gibson hydro plant in Oklahoma.
A common problem with digital excitation systems is that after a certain time, 15-20 years, the original equipment manufacturer (OEM) will have a problem to supply spare parts, due to obsolescence of the original microprocessors. After all, microprocessor suppliers have little interest in supplying technology that is 15-20 years old.
A common misconception is that only the OEM is able to undertake this type of upgrade. However, in this case, the customer, US Army Corps Of Engineers (USACE), issued an open Request For Proposal (RFP) to replace the ABB UNITROL F excitation control equipment and invited multiple vendors including the OEM.
After a thorough evaluation of the submitted tenders, considering technical, quality and experience etc, it was determined that Reivax North America was ranked the highest and subsequently an award was issued accordingly.
The success story provides more in-depth explanation of how REIVAX successfully extended the life of their excitation asset by upgrading the control section with new RTX Power excitation controls
REIVAX RTX Power static excitation system is used in hydro and non-hydro generating plants as well as for synchronous motor applications.
Feel free to contact our sales team if you have a UNITROL F or UNITROL 5000 excitation system that needs to be upgraded.
