综合工业监控网络在电力系统中的应用

分析了当前电力系统监控网络中存在的问题,提出了解决方案———应用可兼容多种总线结构和协议的协议自适应方法,建立以以太网为中心的,多层次多协议结构并存的综合工业监控网络。介绍了综合工业监控网络的软硬件结构,分析了整个网络中不同结构之间的数据冗余、流量控制和安全等问题。运行结果表明,该网络能更好地进行现场设备控制和管理,为实现真正用户终端级的、高安全性的控制提供了一个新的解决方案。图5参6

Application of Comprehensive Industry Monitoring and Control Network in Power System

Problems existing in monitoring and control networks of current power systems are being analyzed. For solving these problems, a comprehensive industrial monitoring and control network has been developed, with a multilayered multi-protocol coexisting Ethernet based structure by making use of the protocol self-adaptive and multi-bus tolerating method. Soft and hardware structures of the network being explained, and questions concerning data redundance between different configurations, flux control and their security analyzed. Operation results show that with this network, on-site equipment control and management becomes more convenient, which provides customers with an actual user-terminal class control of high security.
