The Shandong Quancheng 1000kV substation is a hub substation of Shandong Province's super grid and the receiving substation of the Ximeng Shandong ultra-high voltage AC project. The original 110kV area of the substation was equipped with ordinary density relays for switchgear such as Xidian and ABB. Langsongkeli upgraded the equipment pressure status through digitization and uploaded it to the four party comprehensive automation monitoring platform in the station through the IEC61850 protocol, providing real-time, intuitive, and effective equipment condition judgment for operators.
