摘要
随着电力系统的重要性越来越高,仿真作为预防事故的重要手段也显得尤为必要,为提高仿真效率一般将仿真区域外的系统做一个等值,而目前常见的两种等值方法Ward等值法和网络等值法各有优缺点且无法满足大系统多节点的要求。针对以上问题,本文提出了一种基于动态分区的电力系统电磁暂态仿真外部系统等值方法,用来满足大系统多节点情况下的仿真需求,并提出了存在的问题及未来的发展趋势。
Due to fact that the importance of electric power system is higher and higher, the simulation as an important means of accident prevention is very necessary. In order to improve the simulation efficiency, an equivalent area is generally used for simulation system. Two common equivalent methods, Ward equivalent method and network equivalent method, have its advantages and disadvantages and cannot satisfy the requirement of large system more nodes. This paper, to solve above problems, according to a research unit based on the research and development of dynamic partitioning of power system electromagnetic transient simulation software, studies the use of two kinds of common external system equivalence method and dynamic partitioning method, and puts forward the existing problems and future development trend.
