中文摘要：
源流路径电气剖分理论研究电力系统各类电源和各类负荷之间的供受电关系问题,剖分得到的子网络包含了平衡点的发电机和网络以及负荷的相关参数及信息。为研究包含网络及负荷等参数的系统阻尼问题,基于该理论建立发电机3阶和5阶模型下的子网络小干扰稳定阻尼分析模型,并通过仿真计算与模态分析技术方法进行对比。结果表明,该方法建立的阻尼分析模型能较好地筛选出系统中的弱阻尼机组。由于模型中包含了网络详细信息,有助于同时研究机侧和网侧工况对系统阻尼的影响,为研究机组阻尼分布及其发展变化过程创造条件。
英文摘要：
The electrical dissecting theory of path between source and flow studies the supply-receiving relationship between different sources and different loads.The sub-network obtained by dissecting contains the relevant parameters and information of generator,network and load at the balance point.The stability analysis model is established based on this theory with the third and fifth order equations of generator to study the power system damping for the sub-network with small interference.Results of simulative calculation are compared with those of mode analysis,which shows that,the weak damping units are accurately picked out by the proposed damping analysis model.As the detailed network information is included in the model,the effect of operating conditions at both generator side and network side on system damping can be studied at the same time to research the generator damping distribution and its variation.
