摘要
对实际电力系统进行电磁暂态仿真,往往耗时很长。如何有效地对外部系统进行等值以减小仿真系统的规模,长期以来是电磁暂态仿真研究领域中的一个重要课题。对该领域迄今为止主要外部系统等值方法进行了分类,给出了各类方法的基本过程,分析了其优缺点;并对该领域今后的发展趋势及关键问题的突破作了展望。
Electromagnetic transient simulation of an actual large-scale power system usually takes long time. How to achieve the equivalent circuit for the external system and reduce the simulation system scale has all long been one of the key topics in the field of electromagnetic transient simulation. So far the main external system equivalent methods in this field are classified, and the main content and process of each method and its advantages and disadvantages are described and analyzed. Finally, a look-ahead for the development tendency and the key issues of the external system equivalent methods to be broken through for power system electromagnetic transient simulation are presented.
