Abstract
The nonlinear robust control problem of power systems is investigated in the paper. A novel controller for the generator excitation system is set up, based on a combination of H∞ control theory and an exact feedback linearisation approach. The properties of the controller are its complete decentralisation and robustness. The design is well suited to a multimachine system in that it is not based on a infinite bus approximation. Simulation performed on a 13-machine system shows that the proposed controller can not only improve the dynamic performance of the power system but also enhance the system stability, especially the large disturbance stability.Keywords
