ASE61850 SCL Manager – Comparing Top-Down and Bottom-Up Engineering for IEC 61850 Substations

By ASE UNTIL, MAR 5, 2022

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.
