Substation Automation Standard
Reducing engineering costs using IEC 61850
BY ADAM GAUCI, Schneider Electric
As substation automation is moving towards software environments based on the International Electrotechnical Commission’s substation automation standard, IEC 61850: “Power Utility Automation”, the engineering process is becoming more complex. Consequently, a greater portion of the capital expenditure (CAPEX) budget is used to develop new—or upgrade existing—substations, especially in interoperable, multi-vendor environments. This can be attributed to the increasingly complex automation schemes which are now...
