摘要
通过引进作用一角度变量（Ｉ，θ），在辛变换下运用Ｍｅｌｉｋｏｖ方法，研究了具有双自 由度特点的电力传输线系统的混沌振荡问题。证实了在平稳风力作用下，传输线振荡现象蕴 含了混沌特性，为认识和控制其振荡提供了理论依据和解析计算方法。
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.
