The interaction between the natural oscillatory characteristic of a nonlinear system with a periodic driving source gives rise to oscillations whose frequency depends on the amplitude of the oscillation. The existence of combination tones (both harmonic and subharmonic) in such systems, gives rise to complicated oscillatory behaviour induced by either the occurrence of the saturation of transformer cores or by system conditions leading to the reduction in the magnitude of damping. By studying the frequency characteristics (Bode plot) of single phase nonlinear power networks, the possible oscillatory modes that may be excited can be anticipated. This aspect is then extended to three phase power networks to include the influence of mutual coupling between phases and unbalance due to non-transposition of transmission lines. The Frequency Scan feature in the Alternative Transients Program (ATP) is used for that purpose. |
