摘要
针对电力系统分析综合程序(power system analysis software package,PSASP)中现有的用户自定义(user-defined,UD)建模功能存在诸如方便性、灵活性、计算精度、仿真效率等方面的不足,笔者对其进行了优化升级,以进一步满足用户进行大规模电力系统仿真分析的需要。为此,提供了2种优化措施,一是采用一种拓扑结构排序算法,即Kosaraju算法;二是引入用户自约定临时变量。最后,通过PSASP中36节点机电暂态算例和小干扰稳定算例对2种优化方法进行验证,算例结果证明了该方法的有效性。
In allusion to insufficiencies in existing user-defined modeling function of power system analysis software package（PSASP） such as expedience,flexibility,calculation accuracy and simulation efficiency,the optimization and upgrading of the user-defined modeling function were performed to further meet the requirements of PSASP users in simulation analysis of large-scale power grid.Two optimization measures were provided： one of which was the adoption of a kind of topological structure sorting algorithm,namely the Kosaraju algorithm,to form reasonable computation sequence,and the another one was leading in user-defined temporary variables.The improvement of simulation efficiency and calculation accuracy by the proposed optimization measures was verified by an electromechanical example of a 36-bus system in PSASP and a small signal stability example of 36-bus system in PSASP respectively.
