Investigation of the Performance of of SynchronousGenerators Equipped with Nonlinear ExcitationController
2016
Investigation of the dynamic performance of a synchronous generator connected to an infinite bus (SMIB) system is carried out
in this paper. The generator is equipped with a nonlinear excitation control law based on the concepts of geometric homogeneity and
feedback linearization. A new positive parameter, called the dilation gain, is introduced in the control law for improved damping of
oscillations and better dynamic performance. Two models of the system are employed for the study, and a disturbance in form of a network
fault with varied durations is applied to test the performance of the system. Simulation results as well as MATLAB® code for testing for
exact linearization of an affine nonlinear system are provided.
