A dynamic simulation model for a twin-shaft industrial gas turbine is presented. The model is of modular design. Each component is modelled individually. This allows the model user to modify selected items without having to remodel the complete system. The model allows the simulation of a complete operation cycle from start-up via part load, full load operation and load drop. Simulation results of 14 selected operating points have been compared with measured values from trial test runs. 65 % of the calculated values do not deviate more than 2 % from the referenced values, and over 90 % of all simulated values are located in a tolerance band of less than 5 %. The dynamic response of the model is demonstrated by comparing the measured speed response during a load shedding test with the respective simulation result.
