摘要
本文讨论电力系统受负荷或线路阻抗小扰动的复杂振荡行为。建立了它的数学模型,用Melnikov方法导出产生各种振荡现象的条件,得到相应的结论。研究指出:电力系统可能存在复杂振荡现象而不失步的情况.本文为解释和认识电力系统的振荡机理提供了一种可能的理论分析.
This paper discusses the complicated oscillation behavior of power systems affected by small perturbations of load or transmission line impedance. The mathematic model is established. The Melnikov method is used to introduce the conditions in which various oscillation phenomena occur. The corresponding conclusion is made. The study shows that complicated oscillations may exist in power systems which do not lose synchronization. The work of this paper provides a theoretic analysis way to understand the oscillation mechanism.
