The effects of response ratio of excitation system on the stability of different power systems are discussed. The excitation system which has high response ratio and high transient gain can effectively improve the stability, in especial with weak tie-line and/or with local load.The calculation result shows that the level of dynamic stability is higher than the transient stability when a power system stabilizer(PSS)is installed. The parameters of PSS must be selected to increase the damping of the system,...

本文介绍了励磁系统响应速度对电力系统稳定的影响。对于经长距离线路输电的发电机,采用装电力系统稳定器(PSS)的高增益,高响应励磁系统有利于提高电力系统稳定。当送端带地区负载,或两大系统之间的联系薄弱时尤其如此。计算结果表明加PSS励磁系统可使系统的动态稳定水平高于暂态稳定。在选择PSS参数时主要考虑能有效的增加系统阻尼,但也要对暂态稳定的影响进行校校,使其有利于暂态稳定。

This paper comprehensively studies the jump, catastrophe, bifurcation and chaotic phenomena of weak-tie connected power systems disturbed by small periodic load power. The mathematic model and two chaos models of weakly connected power systems are established. The conditions in which bifurcation and chaos occur are obtained by Melnikov Method.The result of this paper indicates that the often-used Small Disturbance Method incompletely reflects the behavior of power systems affected by small disturbance.Nonlinear Dynamics Theory can provide a new way to study power system oscillations.

本文利用现代应用数学的研究成果,对弱联电力系统在弱周期负荷功率干扰下的跳跃、突变、分叉和浑沌现象作了较全面的分析,建立了弱联电力系统的数学模型及两种典型浑沌模型。文中采用Melnikov方法导出了电力系统产生分叉与浑沌的具体条件。理论推导及分析与电力系统的物理概念和实际情况相符,为电力系统振荡行为的研究提供了新的思路和途径。

In this paper, the Melnikov method was used for the first time to analyse the chaotic power oscillation on the weak tie line which is caused by the disturbance of two periodic loads. The conditions of producing chaotic power oscillation in ppwer system was obtained. The numerical calculation results showed that in chaos existing regions, the stochastic power osillation on tie line might occur as the determinate load disturbances exist.
