TC&E offers REAL turnkey solutions for retrofitting aging excitation systems. With the ability to upgrade most excitation control systems up to 6000 field amps, TC&E can evaluate your system and suggest a turnkey solution that best fits your plants application and budget. Whether a DFE or Complete system rip and replace, TC&E will work with your team to determine the best solution for your plant.

Most often a Digital Front End Upgrade using Basler DECS Series AVR’s is the easiest and most economical solution. TC&E has installed dozens of Basler DECS AVR’s, from Hydro’s to Large Steam applications. TC&E and Basler have developed a relationship that ensures the quickest response from the Engineering Support team and Product Delivery.

In most circumstances the Exciter Bridge and SCR Components are long lasting and require very little maintenance and repair. The AVR Portions of the exciter control the voltage regulation and communications to the turbine control panel. These are typically computer processor based and have become slow, old and obsolete just like your older home computer systems.

By upgrading the AVR with a Digital Front End, you bring your Exciter back to the most modern levels of reliability and ensure safe and consistent generator control.

In today’s world of NERC Compliance and ISO Capacity reliability requirements, upgrading to the latest Digital Technology offered by Basler and other AVR Manufactures is the REAL solution to ensuring operational readiness and NERC Compliance.

In most cases, a digital front end upgrade is the best option to keep excitation systems up to date and reliable. In some cases, such as brushless systems, it can be more cost effective to replace the complete excitation system. TC&E designers will work with your team to determine the most cost-effective solution for your upgrade needs.
