摘要 摘要 随着数字化变电站的发展,IEC61850规约必将成为未来电力系统的统一规约。 如何将现有的使用CDT、101、104等规约的常规变电站纳入到IEC61850通信体 系中,是实现常规远动通信体系向IEC61850通信体系过渡的重要课题。而规约 转换器则是解决这一问题的关键技术。本文针对一个抽象出的过渡期典型变电站 自动化系统,设计出一种基于IEC61850建模的面向对象的新型规约转换器软件。 经测试该软件能满足实际应用的基本性能要求。 本文通过将IEC61850、CDT、101、104分别分解为功能和信息表、物理层、 链路层、应用层等四方面,对这几个规约进行了简单的对比分析,建立了初步的 映射关系。这种映射关系是建立公共数据库的基础,公共数据库的数据项为传统 规约的遥测、遥信等数据影射到IEC61850相应逻辑节点模型的集合,公共数据 库是联系各规约的关键组件。然后运用软件工程的方法,对规约转换器进行了面 向对象分析和面向对象设计,面向对象分析得出了规约转换器的对象模型、动态 模型和功能模型,面向对象设计划分了规约转换器的数据管理子系统和问题域子 系统。接下来进行了各子系统的详细设计,数据管理子系统的设计得出了公共数 据库的简单形式,问题域子系统则进一步分解成IEC61850子站、CDT、101、104 等四个模块,给出了各模块的详细设计方案。最后将整个设计方案用C++编程实 现,并进行单元测试和集成测试,验证了方案的正确性和可靠性。 运用面向对象分析和设计方法对IEC61850规约转换器进行设计是本文所作 的有益尝试,设计方案和运行结果证明面向对象的新型规约转换器具有良好的可 靠性及可扩展性。同时,本文设计的IEC61850规约转换器功能还不完整,IEC61850 规约标准的规模很庞大,本文只根据规约转换需要实现了其中的一部分,要完整 实现IEC61850规约还有大量工作要做。本文的工作为IEC61850规约转换器的 进一步扩展研究打下了良好的基础。 关键词:IEC61850:规约转换;面向对象

ABSTRACT testing to verify the program's correctness and reliability. Using object-oriented analysis and design method for the design of the protocol converter is a useful attempt made in this paper,the design of programs and the results prove that the new object-oriented protocol converter has good reliability and scalability.At the same time,the paper's design features of the protocol converter is not complete,especially the part of IEC 61850 protocol,because of its large-scale, this paper only realized a small part of IEC 61850 in accordance with the need for conversion,the full realization of the protocol converter is still need much work to do, the work of this paper can be used as a basis for further expansion.
