When operating real gas turbine power plants in industry, the specified process parameters must be strictly adhered to. In order to be able to start a real plant, the start values are specified. Incorrectly selecting these values can prevent start-up or cause damage to the plant. Critical speed ranges must be passed through as quickly as possible. When operating a plant, certain operating conditions must be avoided in order to prevent damage to the plant or the environment.
The ET 795 experimental unit is a pure simulation device. It is controlled and analysed by means of the software provided. The advantage of a simulation gas turbine power plant is that boundary conditions can be passed through safely and the plant’s response can be studied without causing any damage to the plant. The plant’s response can be tested by carefully changing the process parameters.
Nine different process parameters can be set via potentiometers on the control unit of the experimental unit. The process parameters control the software. The process parameters include temperature, pressure and pressure ratio as well as the efficiency of the individual components. The mass flow rate and pressure of the fuel, the air supply as well as the load of the generator are also adjusted via the potentiometers.
The software offers various display options. The change in the plant’s overall efficiency resulting from the set values can be observed in the software. The fuel-air ratio λ, the power at the drive shaft of the compressor and at the generator as well as the pressure ratio of the compressor can be calculated in the software.
The experimental unit is connected to a PC via USB.
