【摘要】 该文从软件工程的角度介绍了可用于大型互联电力系统的小干扰稳定分析软件包的开发思想。由于基于QR算法的小干扰稳定分析软件对计算规模的限制 ,开发新的适合大规模电力系统的、可详细建模和变换不同特征根算法的软件包是电力系统计算软件发展的必然。基于面向对象 -设计模式的概念对本质结构进行分析 ,找到软件系统中的凝聚点 热点与设计模式中的模板 挂钩的对应性 ,从而在软件编制中顺利地应用了设计模式的通用原则 ,使所开发的软件包可随意变换多种不同的算法 ,其适应性较好。此外 ,从改进元件联结法 (CCM)所建立的电力系统小干扰对象模型中基金项目 :国家重点科技攻关项目资助 ( 97 312 1 11 1e)。ResearchKeyProjectoftheNationalNinth fiveYearProgramofChina( 97 312 1 11 1e) .抽象得到“多类型对象连接图”的设计模式 ,并进行了定义。使用该定义便于对不同详细程度的模型进行调用 ,而且分层递阶关系清楚更多还原

【Abstract】 The paper introduces a novel idea for the development of the Small Signal stability Analysis Package (SSAP) which is applicable to large scale interconnected power systems.The software package consists of detailed and simplified generator models and different numerical algorithms other than QR method which is limited in system scale.Based on the concept of objective oriented method and design pattern,and the analysis of essential structure,the correspondence between the stable spot hot spot in software system and the "template hook" design pattern is found such that the general principle of design pattern is fully used.Hence,variable different algorithms could be invoked by the software package.Furthermore,the "multi type object connection figure" is abstracted from modified Component Connection Modeling (CCM) and well defined.Therefore,the models at different level of detail could be called and the hierarchical relationship is clear.更多还原
