The Dunamenti Power Plant in Százhalombatta, Hungary, is the largest gas-fired power plant in the country with a capacity of 794 MW, making it a major source of reliable electricity in Hungary. Recently, in collaboration with the customer and plant owner, MET Asset Management AG, and within the scope of an overhaul project, Siemens Gas and Power replaced the entire rotor of the plant's SGT5-2000E gas turbine and installed a new, state-of-the-art SPPA-T3000 control system.

The rotor exchange for the SGT5-2000E at the Dunamenti Power Plant led to an increase in output from 148 MW to 155 MW and increased the unit's efficiency by approximately 0.8 percent. The turbine had already achieved 120,000 hours of operation and, with the new rotor, is now ready for the next 41,000 hours before the unit's next scheduled outage services.

In addition, the complete instrumentation and control system was upgraded to Siemens cutting-edge SPPA-T3000 R8.2 control system. The gas turbine modernization was the first of its kind worldwide using new ET200 SPHA hardware, which ensures a significantly higher signal density, redundancy possibility, better sensor monitoring and includes faster input/output design groups with the best signal/price values. This innovative control system also provides a solid foundation for increased cyber security, system integrated full redundancy, compactness, and easy handling. Patches and updates can be easily implemented online, without any interruption of plant operation and monitoring. The engineering and installation were executed by Siemens Zrt.'s team of experienced Hungarian engineers, while also onboarding dual MsC students in order to widen their knowledge as well. The engineering and installation of the new solution was carried out cabinet tests were also conducted at Siemens Hungary's headquarters in order to help ensure fast reaction times and close collaboration with the customer.
