Design and Implementation of 220kV Intelligent Substation
This article mainly explores the design points and functional implementation of Lingquan 220kV intelligent substation.The substation adopts a three-layer architecture of process layer,bay layer,and station control layer.The communication between equipment in the station follows the IEC61850 standard and GOOSE fast message transmission mechanism,ensuring communication speed and information sharing.In the selection of hardware equipment within the station,optoelectronic current transformers with good insulation performance and high measurement accuracy were selected,as well as intelligent terminals that support auto matic reclosing and automatic interlocking.This intelligent substation has advantages such as stable signal transmission,saving land area,and improving automation management level,achieving unmanned operation of the substation.
