【摘要】 电力稳定控制系统的软件设计存在实际需求复杂多变、项目合作困难、开发工具限制等问题,统一建模语言(UML)提供了标准的建模方法。使用UML对电力稳定控制系统的软件设计进行需求分析和系统设计,详细描述了系统任务的用例图、工作过程的顺序图、功能组成关系的包图、稳定控制逻辑模块的工作状态图。将该系统抽象为一组对象模型,由数据采集、异常判别、故障识别、故障策略处理、通信功能5部分组成。这些对象具有良好的扩展性能,并通过对对象模型的静态与动态关系分析,建立了系统控制层、业务逻辑层、数据服务层的3层结构的最小实现系统模型。更多还原

【Abstract】 Software design for the electric power stability control system often encounters different obstacles,such as complex practical demand,difficult project cooperation,tool limitation and so on.UML(Unified Modeling Language) provides a standard modeling way for it.Requirement analysis and system design are performed with UML and the use case diagram for system task,the sequence diagram for working process,the package diagram for function composition and the work state diagram for logic unit are presented.A group of object models with good expansibility are constructed,consisting of data sampling,exception identification,fault identification,fault strategy and communica-tion.By static and dynamic analysis of these models,a 3-level minimum realizable system model of system controller,logic function and data server is set up.更多还原
