变电站自动化技术经过十多年的发展已经达到一定的水平,不仅中压变电站采用了自动化技术实现无人值班,而且在220千伏及以上的超高压变电站建设中也大量采用自动化新技术,从而大大提高了电网建设的现代化水平,增强了输变电和电网调度的运行管理水平。 Substation automation technology has reached a certain level after more than a decade of development. Not only has the medium voltage substation adopted automation technology to realize unattended operation, but also has adopted a large number of new automation technologies in the construction of 220 kV and above EHV substations, Improve the modernization of power grid construction and enhance the operation and management level of transmission and distribution and grid dispatching.
