变电站综合自动化技术发展趋势

Development Trend of Integrated Protection and Control in Power Substations

本文介绍了变电站综合自动化的发展动向，分层分布式的控制系统，并且对计算机网络的选用原则、子站的设计等问题进行了讨论，最后概括了综合自动化系统的主要优点。

The latest developments of integrated protection and control systems are introduced. The main trend,according to the author's view, is distributed control system with Local Area Network(LAN). Some of the key points,for instance the selection of LAN, design principles of the bay level nodes are discussed,and finally the main advantages of such systems are listed.
