摘要
利用非线性动力系统的基本理论 ,并借助于一个简单的电力系统 ,给出了电力系统中导致混沌出现的两种不同的途径。运用Piocar啨截面和Ｐｉｏｃａｒ啨映射技术 ,深入研究这两种途径的表现形式、内在规律、引发机理 ,并进一步讨论了它们与电力系统扰动间的关系。由于混沌现象存在时 ,系统运行参数将伴随持续无规则的振荡 ,这在电力系统运行中是绝对不允许的 ,而弄清楚混沌的产生机理 。
In this paper, two routines to induce chaotic attractor in power systems are reported based on nonlinear dynamical theory.Using Piocaré Mapping and Piocaré Section, the descriptions, the characteristics and the causes of the routines are deeply studied. Moreover, relationships between the routines and system disturbances are further discussed. Chaos is one type of continuous and random oscillation in power systems, and is absolutely forbidden. So, to entirely get hold of all the routines to the chaos in power systems is very helpful and necessary to prevent this abnormal phenomenon.
