Combined cycle gas turbine plants

With an electrical efficiency of up to 60 percent, combined cycle gas turbine plants are among the most efficient conventional power plants. This efficiency is achieved by a thermodynamic cycle where a gas turbine and steam turbine are combined with a waste-heat recovery boiler. Thanks to short start-up times and quick load changes they also enable flexible power plant management.

BNA has plenty of experience when it comes to providing electrical, process control and instrumentation technology for combined cycle gas turbine plants. BNA is also familiar with all parts of the plant from feed water provision, steam generation and distribution through to condensate treatment as well as fuel and air supply. Sophisticated solutions for controlling the water-and-steam cycle, supply air and exhaust system and fuel supply ensure short commissioning periods and robust operation. BNA has developed safe migration strategies for renewing the process control technology during ongoing operation, keeping down-times to a minimum and ensuring a safe restart.

Thanks to tried and tested power unit control solutions, BNA is able to support automated power plant operation and help operators optimise their power plants in accordance with the EEG (German renewable energy act) and in terms of the provision of operating reserves.
