电力系统数字仿真模型研究

Study on Power System Digital Simulation Model

文章以电力系统中最常见的3种电气设备:同步发电机、输电线路和变压器为例,对数字仿真模型进行介绍和分析。分析结果表明,在构建仿真模型中必须根据研究的目的、对象以确定模型的类型。同时,在确保仿真准确性的基础上,要采用相应的措施,以提高仿真的工程实用性。

In the paper, the digital simulating models of three common electric equipments are intro- duced and analyzed, they are synchronous generator, transmission line and transformer. From analy- sis results, the type of simulation model should be determined by the research purpose and the practi- cal condition of research object. Furthermore, related measures should be taken on basis of ensuring simulating accuracy, and then project practicability of simulating model could be improved.
