摘要
在已有的静态、综合负荷模型等常用模型的基础上,通过应用仿真软件中已有的标准负荷模型,借助双区域四机典型网络,在对系统分别施加小扰动和三相故障的条件下,运用Prony法分析发电机功率曲线图,得到采用不同负荷模型时各个发电机的振荡模式、振荡频率和阻尼比,进而比较不同形式的负荷模型对于系统动态过程的影响。研究结果表明,负荷模型对于系统的动态过程有着重要影响。
In this paper, on the basis of the existing static and composite standard load models, with 2-zone 4-machine typical network, small disturbance and the three-phase fault are applied to the system. By using Prony analysis for generator power curves in different models, this paper obtains each generator＇s oscillation mode, the oscillation frequency and damping ratio, and compares the effects of different load models on system dynamic process. The results show that the load model has a significant impact on the dynamic process of the system.
