Analyzing the Influence of Induction Motor Inertia on Power System Low Frequency Oscillation

The influence of inertia constant (H D ) of induction motor on low frequency oscillation (LFO) is studied by integral manifolds theory. The oscillation frequency and the damping ratio are formulated in single-machine infinite bus (SMIB) system. The theoretical analysis shows that H D influences mainly the damping of LFO, the extent of which is related to the system structure and initial operating condition. The eigenvalue analysis of SMIB system and a simple two-area system shows the influence of H D on local and inter-area oscillation modes of LFO. The results of full-order system and reduced-order system by integral manifolds theory are compared.
