| Abstract: | Through introducing action --angle variables (I, 8), under Xin transformation, use the Melnikov method to discuss the chaos oscillation problem of the power transmission lines system with two degrees of freedom. Under the smooth wind-force action, we proved that the phenomena of the transmission lines oscillation implicate chaos property. The theory basis and analytic calcaulation method are provided for recognizing and controling the oscillation. |
