变电站综合自动化系统体系结构研究

在分析了常用变电站综合自动化系统的结构、特点以及常用系统不足的基础上，提出了一种基于4层结构模型的变电站综合自动化系统。它实际采用的是一种分层的功能模块化设计思想，硬软件可做到模块化、通用化，能根据不同类型变电站的一次接线方式实现不同的系统配置。整个系统的可靠性较高，可维护性和开放性较好。文中较详细地阐述了该系统的构成和原理。

STUDY ON STRUCTURE OF INTEGRATED SUBSTATION AUTOMATION SYSTEM

The structure and features of integrated substation automation system in common use are analyzed. Based on the analysis of the insufficiency of usual integrated substation automation system, a new integrated substation automation system on the basis of the model with four-layer architecture is put forward, and the layered function modularization design idea is applied to developing this system. Furthermore, with the modularization and universal of software and hardware, the configuration of system will be diverse according to the connection ways of primary equipment in different type of substation. The reliability, maintainability and opening of new system are improved. The structure and principle of this system are expounded in the paper.
