IEC61850 Engineering process recommends and illustrates a top-down flow starting with a substation specification or SSD. However practical implementations on the ground in pilots, as well as live stations, sometimes employ a bottom-up approach. See how these two different approaches work and the salient similarities and differences between them using a proven third party SCT.
