This paper proposed a hierarchical model for smart substation fault diagnosis. This fault diagnosis system gets fault information from SCADA and fault information system. The information from SCADA, including network topology and switch state, is modeled based on IEC61970-CIM. The protection information from the fault information system is modelled based on IEC61850, then encapsulated CIM model. When...
In general, modeling the behavior of the core in current transformers (CTs) used for protection and the effects of its operation outside the linear region are commonly reported in literature. The problem in using a mathematical TC model is to obtain the parameters in a particular case in order to implement that model easily, efficiently and accurately. In this sense, a CT model was implemented in...
Major features of IEC 61850 include SCL-based engineering, uniform data model and communication-based information transfer. Owing to XML-based characteristics of SCL, a substation engineering can be done easily with programming. There are four kinds of information file in the SCL-based engineering - SSD (System Specification Description), ICD (IED Capability Description), CID (Configured IED Description)...
