IEC61850标准是电力系统自动化领域唯一的全球通用标准。它通过标准的实现，实现了智能变电站的工程运作标准化。使得智能变电站的工程实施变得规范、统一和透明。不论是哪个系统集成商建立的智能变电站工程都可以通过SCD（系统配置）文件了解整个变电站的结构和布局，对于智能化变电站发展具有不可替代的作用-IEC61850 standard is the only universal standard power system automation.It through standard implementation, realize the intelligent substation project operation standardization.Makes the project of intelligent substation specification, unified and transparent.No matter which system integrators to establish intelligent substation project can all be SCD (system configuration file to understand structure and layout of the whole substation, has an irreplaceable role in the development of intelligent substation
