The DNA of the substation

IEC 61850 is more than just an international standard for the vendor-neutral description of devices in substations and with specifications on how these devices may communicate. It forms the DNA of the systems, so to speak; entire congresses are devoted solely to it, and it causes headaches for operating companies. This is because the digital substations of the future, which now need to be planned quickly and in large quantities due to the enormous pressure to decarbonize, will mainly contain servers instead of rows of control cabinets. Data bus systems then handle the exchange of information from the field to the control system. This makes IEC 61850 even more important.

Without the physical wiring of the devices, circuit diagrams or terminal block diagrams are also no longer required. As a result, document-oriented engineering tools that rely on circuit diagrams for detailed information are becoming much less important. "Thanks to data centering, EB can also work purely alphanumerically. There is no need to draw a single plan to define details," explains Imbusch.

A big step

EB has been supporting IEC 61850 for years: by integrating the Substation Configuration Tool (SCT) developed by Aucotec partner H&S, by understanding the required Substation Configuration Language SCL and by being able to generate the normative SCD file (Substation Configuration Description). "With the new big step, EB can do all this on its own, without XML outputs and transfers or tool synchronization. The functional data models of the Intelligent Electrical Devices (IED) are directly linked to their hardware models. The system landscape is now significantly streamlined and the strain on IT is reduced," emphasizes Michaela Imbusch. Linking the hardware and software worlds is also a considerable relief for project managers. "Always knowing where the data is and being able to rely on it being up to date is anything but a matter of course," says the product manager.
