The % complete system is modeled using SimPowerSystems(TM) % and Simulink(R) blocks. The controller is based on a feedback linearization scheme. Its main goal is to control the rotor angle as well % as the terminal voltage, to improve the stability properties, and to obtain good dynamic response. % % The performance of the nonlinear controller is tested on the nonlinear turbine-generator system. The controller and turbine are % simulated using Simulink blocks while the generator is represented by the Synchronous Machine block from the powerlib library. % A three-phase short-circuit is simulated on the load busbar and the fault is cleared after 100 ms. % %% Simulation % % *1.* Start the simulation. Observe the field voltage Ef, power angle % delta, and terminal voltage Vt. % % *2.* You can observe how the stabilization of Vt is obtained in less than 0.25 seconds with this controller. % The load angle takes longer to stabilize, because the time constant of the mechanical part of the system % is much larger than the electrical time constants. % % *3.* If you want to compare results with classical regulators, replace the nonlinear controller with the same % excitation system and Hydraulic Turbine and Governor block used in the psbturbine example. You should % notice that the system takes longer to stabilize than in this case study. % %% Reference % % Akhrif O., A.F. Okou, L.A. Dessaint, and R.
