A Language for Substations: IEC 61850, Logical Nodes and SCL
Khalid Mansoori, the senior electrical engineer at the Al Sahil Gas Complex, has spent twenty years with substations wired point to point with thousands of copper cores. The new gas trains come with a 132/33 kV substation and an electrical control system built on IEC 61850, and Leila Darwish, the plant's data architect, wants to know why the electrical engineers seem to have a better data model than the process engineers. Together they walk through why the standard exists, what a logical node is, how a whole substation is described in one XML file, and why "IEC 61850 compliant" on a datasheet…
