Digital Substation is an engineering publication focused on IEC 61850 automation, protection systems, and digital grid intelligence.
IEC 61850 interoperability testing is under way in Utrecht, where equipment and software from multiple suppliers are being integrated into common protection, automation and control applications. Participant reports now cover functional protection tests, network configuration from SCD files and virtualised protection.
Conventional CTs hardwired to two multifunction IEDs per 132 kV bay from different manufacturers, GOOSE in place of interlock wiring, a virtualized SCMS, and a standard drawing set that ships with every tender. The design has now supported the construction of 90 substations in Dubai.
To meet the needs of both operational technology (OT) and information technology (IT) networks, SDN is emerging as a superior solution.
