| Abstract: | Bifurcation theory is a useful mathematic method in studying nonlinear system. In this paper, general idea and theory of bifurcation is introduced, and nonlinear singular phenomenon in LFO (Low Frequency Oscillation) of a single-infinite power system is analyzed based on Hopf Bifurcation Theory. A new conclusion was reached which is different from that of a conventional linearization analysis, and it is validated by means of SBS (step by step) method. |
