Modeling Power-Supply Systems with Gas-Turbine Units as Energy Sources

Abstract

Simulation models of power-supply systems with sources based on gas-turbine units with different structures and compositions of components and analysis of their functioning taking into account various technological factors and specifics of the power system are considered. The calculation of the dynamic conditions is represented as a sequential calculation of the static modes at each sampling step. Models of power-supply system components have been developed, including a nonlinear model of a gas-turbine unit and a model of the source of nonlinear distortions. The presented method for calculating the parameters of the models of power-supply system components allows one to model complex modes of power-supply systems powered by autonomous sources. For verification of the calculations, a seminatural model was developed based on the laboratory “synchronous motor–dc motor” setup. The approach proposed makes it possible to improve the accuracy of modeling interrelated processes and to expand the range of the tasks to be solved including modes that are not recorded by instrumental measurements. The results of the scientific and engineering solutions implemented in industrial conditions have good convergence confirmed by seminatural models and instrumental surveys.
