一种新型电力系统通信网关的研制

首先探讨了电力自动化系统通信网关的设计原则,随后详细描叙了新型通信网关WYD800的软、硬件的研制。该网关基于嵌入式设计技术,硬件上采用功能强大的微处理器芯片作为CPU,除了常用的串行口、以太网等基本通信接口配置,还提供通用工业总线用于各种应用的灵活扩展;软件上,选用的实时多任务操作系统WindowsCE可以根据硬件配置量身定制,模块化设计的应用程序易于扩展到更广泛的应用,另外还提供界面友好的组态工具包。并且在整个通信网关设计的过程中充分考虑到硬件抗干扰和软件纠错、容错的处理。在变电站、电厂自动化系统的实

Design of a new communication gateway applied in power system

In this paper, the design principle of communication gateway for power automation system is presented, and then the designs of software and hardware for gateway WYD800 are described in detail. The new communication gateway is based on embedded technology, and takes powerful microprocessor as the central processing unit(CPU). Besides the universal communication interface of two serial ports and two fast Ethernet chips ,it provides a PC/104 socket which is one kind of industry-standard bus for practical expansion. Applications on the tailored RTOS Windows CE are designed in module so as to be updated easily and be adapted to more complex applications, and the provided user-friendly support tool is optional. Furthermore, measures for anti-interference and admissible error are fully taken into account during all the courses of design. The gateway WYD800 is proved real-time, reliable and flexible by applying to automation system of substations and power plants.
