【摘要】 本论文首先对配电子站在配电自动化系统中的作用和地位进行了介绍,在此基础上,对配电子站的国内外研究现状进行了分析,针对目前已应用的配电子站的不足之处,结合新技术提出了新一代配电子站的设计要求。根据配电子站的性能要求,设计出了合理的配电子站硬件系统结构,选出了适合配电子站功能需求的实时操作系统;同时根据配电子站在配电自动化系统中的作用和地位,综合分析了配电子站的应用特点,给出了其应用软件的功能需求和其应用指标。在此基础上采用UML的设计方法对配电子站的应用系统进行了设计。建立了配电子站的对象模型,和其关键动态过程模型。 按照设计方案实现的系统,其性能指标完全达到了设计的要求,验证了设计的可行性和有效性。设计方案有以下几个方面的优点: (1)选用Window CE嵌入式操作系统和其它非嵌入式操作系统相比,系统需要更少的硬件资源,操作系统中的资源可方便裁减,能够保证系统实时性,系统的运行更加稳定、可靠。 (2)系统软件设计采用UML通用建模技术,保证了软件结构的合理性,提高了软件的健壮性和可维护性。 (3)系统中的通道和规约采用动态绑定机制,提高了系统的灵活性。西安理工大学工程硕士学位论文(4)采用多线程方式提高了系统的运行效率。(5)采样嵌入式系统构造的配电子站,系统结构紧凑,成本大大降低。
【Abstract】 This thesis firstly introduces the function and position of the sub control center in the distribution automation system. At the basis of that, analyzes present research of the sub control center at home and abroad, brings forward new generation design request aiming at the defects of the applied sub control center at present. According to the design request, the hardware system structure for reasonable sub control center is worked out ,and the real-time operating system is chosen, for which suits the sub control center’s function demand; meanwhile synthetically analyzes the application characteristics of the sub control center according to the function and position in the electric automation system, together with the function demand and application target of the applied software. Then the sub control center application system is designed out by the UML design method. And the object model of the sub control center is established, with dynamic process in its key model.According to the system achieved by the design scheme the function target comes to the design request completely, which verifies that the design is feasible and effective .The and effective. The advantages of the design scheme are as follows:(1) Choose to use the Windows CE embedded operating system, comparing to other unisex-type operating system this type need less hardware and resourcesin the operating can be cut conveniently, which make the system have real-time quality and the movement movement more stable dependable.(2) Design of the system software adopts UML general use model technique, this guarantees the software structure reasonable, enhances the persistence and protection of the system.(3) Channels and rules in the system adopt dynamic binding mechanism to make the system flexible.(4) The adoption multi-threading model increases the movement efficiency of the system.(5) Adopt the embedded system to construct sub control center, system structure tightly packed, the cost declines consumedly.
