Abstract
In order to standardize the configuration schemes of IED (intelligent electronic device), this paper researches the typical configuration of secondary equipments in 110 kV intelligent substations. With the features of fixed operation modes, there are four typical connection modes in 110 kV substations, including inner bridge connection, line transformer unit connection, extended inner bridge connection and sectionalized single bus connection. Then the typical IED configuration schemes in process-level and bay-level are presented respectively. The schemes have the following characteristics: the merging units digitize analog information collected by conventional instrument transformers; process level information is exchanged by peer-to-peer model; the transformer protection, including merging unit, adopts a redundant configuration scheme; a distributed configuration using the IED with integrated functions of process-level and bay-level is implemented in middle or low voltage bays. The engineering practice shows that this scheme can guide intelligent reconstruction of conventional substation with its economy and advanced technology.关键词
