The substation topology consists of the substation, voltage level and bay nodes. The bay nodes include also the conducting (primary) equipment, which corresponds to the switches, that is, the circuit breakers, disconnectors, and earth switch, of the configured IED. In addition to the substation topology configuration, logical nodes of the IEDs are mapped to proper objects, for example, to support the automatic bay configuration via SCL files in the SCADA system.
At the moment, the IEC 61850 Configuration tool does not support engineering of the substation section. Instead, for example, IET600 can be used for engineering, if needed.
