摘要
Abstract
Aiming at the information opaque problem that caused by hard cable loops are replaced by virtual secondary circuit in smart substation, a solution of visualized circuit monitoring is proposed, which uses the IEDs in process layer and bay layer to determine whether a virtual secondary circuit is abnormal and generating abnormal signals, then the signals are sent to station layer by data transmission channel of the integrated supervision and control systems in the form of telesignalling, finally, the abnormal signals are received and analyzed and displayed by the station layer. Based on the research of IEC61850’s short address model, it establishes the mapping between telesignalling in station layer and virtual secondary circuit abnormal signals in process layer and the bay layer by short address. According to the usage in smart substation, the solution is very helpful to operation and maintenance personnel, it solves the lack of means for monitoring on virtual secondary circuit state, and is convenient to find and locate the problem.关键词
