The Selection And Application Investigation Of Primary Equipment In Smart Substation

In this paper, the smart substation's information, automation, and interactive is as the goal, smart grid related technology guidelines, rules and intelligent technology's status quo is as the theoretical support, development and application of substation smart equipment is investigated, and the typical smart substation implementation is achieved. Smart switching devices, electronical current&voltage transformer, online monitoring equipment are detaily investigated mainly from the configuration, function, needs, implementation and other aspects, furthermore, existing problems and development trend is forecastd. In the case of fully study on the development of smart devices and consider the reliability and economy of smart devices, a 500kV substation smart design blue print is put forward, which provides an important reference for smart substation implementation in future.
