The Valmet DNA Gas Turbine Performance Monitoring application provides power plant personnel with valuable information about the performance, condition and operating efficiency of their gas turbines – both in real time and retrospectively. With constant monitoring and analyzing of essential gas turbine parameters, the solution brings increased efficiencies and cost savings to each step of turbine operation.
The Valmet DNA Gas Turbine Performance Monitoring application continuously calculates, displays and stores main gas turbine parameters. Calculations include gas turbine heat balance – with inputs, outputs and losses – and other key performance parameters. These cover inlet temperature, specific fuel consumption, heat rate, thermal efficiency and electrical efficiency. The application also includes the gas turbine wash monitoring feature for maintenance planning purposes. All calculations are built in accordance with generally accepted gas turbine standards, such as EN or ASME.
The application helps power plant maintenance and operating personnel detect potential problems in gas turbine operation and analyze those that have occurred. This prevents failures proactively – before they cause unpredicted shutdowns.
Additionally, extensive storage of history data enables long-term monitoring of gradual component deterioration, for significantly improved maintenance planning.
The tool’s customized user interface includes all essential gas turbine performance data shown in clear and easy-to-use reports and displays. The application is seamlessly linked to the overall automation applications, guaranteeing efficient collaboration between plant management and plant control.
