在充分调研的基础上,论述了目前变电站自动化系统的应用现状,指出其主要结构形式为分布集中式和分散与集中相结合2种类型;现有自动化系统有其自身的不足之处,已逐渐不能适应电力系统的需要,以变电站自动化系统的整体数字化、信息化为目的,提出其发展的前景是数字化变电站;分析了数字化变电站自动化系统的特征、逻辑结构、建设效果以及建设中需要考虑的新问题。
On the basis of full investigation and research, this paper discusses the current application status of substation automation system, and points out that the main structure of the substation automation system has two types: centralized distribution and decentralized integration; the existing automation system has its own shortcomings, It can not meet the needs of power system. The purpose of this paper is to develop digital substation based on the overall digitization and informationization of substation automation system. The characteristics, logical structure, construction effect and new problem.
