摘要
电力系统的低频振荡是现代大型互联系统中的重要问题之一,对它的研究是围绕着振荡阻尼进行的。本文给出了在小干扰下处理现有各种负荷模型的系统方法,其中包括电压或频率相关的静态模型、机理或非机理的动态模型等。从定性、定量两方面分析了负荷的各种动态、静态特性及位置电对力系统低频振荡阻尼的影响。
A systematic method is put forward for dealing with various existing load models under small disturbance,the load model may be static or dynamic,voltage dependent or frequency dependent,induction motor model or I/O dynamic model. According to this method a general program has been made,by which the effects of various electric loads on the damping of LFO in power systems can be analyzed.An illustrative example is given and some valuable conclusions are drawn out.
