现场总线式保护控制综合单元的研究

摘要

The field bus and its application in integrated substationautomation system (ISAS)are described.A new architecture for it, which is object-oriented and based on field bus, is presented. The system is in the line with the basic design concepts of field bus control system and suitable for the application in ISAS. It raises the system design level greatly. The research on object-oriented comprehensive unit for protection and control is emphasized, which is an important part of ISAS based on field bus.%介绍了现场总线技术及其在变电站自动化系统中的应用，提出了一种面向对象的、基于现场总线的变电站自动化系统的新方案。该方案符合现场总线控制系统的基本设计思想，比较适合于当前变电站自动化系统的应用，可在很大程度上提高系统的设计水平。着重对面向对象的变电站自动化系统的重要组成—部分现场总线式保护控制综合单元进行了研究。
