Popis: In this paper, a steady-state phenomenological rigorous model to simulate a gas turbine’s operation that uses biogas from a sewage treatment plant is presented. The model makes use of isentropic efficiencies and operating curves. The model’s parameters were obtained so that the model reproduces the nominal operating point of the gas turbine presented by Franca Junior [1] that uses biogas produced from sewage sludge. Simulations were further performed in order to analyze the effect of disturbances on the operation of the turbine. Perturbations in ambient air conditions and biogas feed were applied, and the simulator successfully solved the simulation problems. Although the gas turbine exhibited a nonlinear behavior, simulation results showed smooth responses. The simulator enables one to understand how each perturbing variable affects the operation of the turbine. Hence, the simulator can be used not only to predict the operations under different operating scenarios but also as a training tool for the operators of sewage treatment plants.
