The Solution for Retrofitting Aging Excitation Systems
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
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
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.
Examples of Retrofit Options
DECS 2100 DFE
GE 7FA EX2000 Dual Bridge upgraded with DECS 2100 DFE. Benefits are the DECS Cores are redundant as compared to EX2000 Primary and Secondary Cores. If the EX2000 main core “fails over” to the Secondary Core, the Unit cannot be started up in this condition. With the DECS2100 Redundant Core Technology, the unit would still be “ready to start”.
Basler DECS 400 AVR
GE 7EA/6B SCT-PPT style Exciters are typically upgraded with a DECS400 AVR system. This takes an older analog system up to the Digital Age and allows system monitoring, trending and analysis. You can add PSS and Fault Capture trending.
Basler DECS 250 AVR
Smaller Steam Turbines and Hydro’s are typically upgraded with DECS250 AVR System.
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.
Using the latest technology, components, and lessons learned through decades of experience, TC&E can ensure complete reliability for both start-up and continuous operation.
Spending good money where it makes the most difference! We understand that O&M budgets are shrinking, so we work with the plants to understand where and when to repair, replace, or upgrade for maximum return.
This is the key to success in today’s competitive power markets. Heat Rate, Capacity, Start-Up, and Maintenance Costs are critical to the success of aging power plants.
Aging systems can continue to provide reliable service for many years to come with the proper service, maintenance, and repairs. Push your upgrades out 5-10 years with confidence.
TC&E always supports MEAG Power with the most experienced field engineers at the right time. whether a planned outage or when things go bump in the night, TC&E has been there for me with the right people or hard to find parts resources when I needed them.
TC&E has always provided a high level of expertise and detail on our site—most notably, custom-tailored projects to reduce parasitic load during the off-peak seasons using logic and controls.
