6 Skyline Drive,
Hawthorne, New York 10532,
United States of America

GTC Control Solutions (GTC), formerly known as Gas Turbine Controls, is a performance-tested controls pioneer, specialising in supplying spares, repairs and services to extend the operational life of ABB, Alstom, Bently Nevada, Emerson, General Electric (GE), Honeywell, Rolls Entronic, Siemens, Triconex, Westinghouse and Woodward control systems.

GTC can upgrade your technology to a more recent legacy system for a fraction of the cost of a new system from the original equipment manufacturer (OEM).

Gas, steam and wind turbine components

GTC maintains the world’s largest stock of spares for excitation circuit boards and components used on gas, steam and wind turbines.

Our multimillion-dollar inventory for GE includes MKI, MKII, MKIII, MKIV, MKV, MKVI, MKVIe, Alterrex, Generrex, EX2000, EX2100, LCI Drive, and Digital Generator Protection (DGP) System, and more.

Inventory beyond GE includes ABB’s Procontrol, Turbotrol, Eagatrol, Bailey Net 90, Infi 90 and BBC Decontic, Alstom’s ALSPA P320, Controcad, Controbloc and TGC, Bently Nevada’s 3300 and 3500, Emerson’s Ovation, Honeywell’s TDC 2000 and TDC 3000, Rolls Entronic’s FT-50, FT-100 and FT-110, Siemens’ SIMATIC and S5/S7, Triconex’s Tricon, Westinghouse’s WEStation and WDPF, and Woodward’s 505/505E, NetCon, and MicroNet.

Power plant testing and repair solutions

In addition to performing functional tests on a number of circuit boards with fully energised panels, we have a state-of-the-art repair facility to ensure all work is performed in a clean and controlled environment.

Some plants have a limited lifespan, which is not economically viable. The repair and remanufacturing solutions that GTC provides not only cuts operational costs but also enables clients to reduce waste.

Our Test & Certification and Repair Services are available for many of the product lines we support and include a detailed Technical Report and Warranty Certificate with an unmatched certification period of up to six years.

Power plant field services and training courses

Our Field Services include health checks for turbine control panels, excitation and LCI, troubleshooting and outage support, TIL review and implementation, HMI or <I> replacement-in-kind, EEPROM backup service, and NERC compliance.

We also offer a variety of training courses carried out by knowledgeable instructors and practicing field engineers. You have the option of predefined seminars or fully customised classes to suit your specific requirements.

Seminars include MKIV, MKV, MKVI and MKVIe engineers and technicians. Courses include MKIV, MKV, MKVI and MKVIe engineers, technicians and operators, on-the-job-training (OJT) and excitation and LCI.

OEM upgrades for power plants

If you require an OEM upgrade, GTC can help you cover the cost by acquiring your pull-out system and spares inventory.

For example, if you own any faulty MKVIe I/O packs (Version H1A) or Controllers (Version UCSA), GTC can buy them or prove credit for any future purchases.

Performance-tested controls

GTC takes the lead in new technologies, we research new resources and apply them in new ways to solve problems. We worry about the controls so you don’t have to.

As the performance-tested controls pioneer, we promise to deliver unrivalled value powered by industrial-strength service.

Inversion Masks: Take Care of Troubleshooting

Contact inputs on GE Speedtronic DS200DTBA boards send +63/-63 DCV to the switched device in the field. If the switch in the device is closed, current flows through the field device and the DTBA card will then annunciate logic 1 for the point, e.g. L33CB1O.
