Substation Digitalization and Next-Level Testing

Grid modernization isn’t just about deployment; it’s about rigorously testing systems to ensure reliability in real-world conditions.

Transforming grid management with IEC 61850

IEC 61850 has become a cornerstone of modern grid management, setting the international standard that powers seamless communication and interoperability within electrical substations. By defining data models and protocols, IEC 61850 lets diverse devices in a substation operate in harmony, regardless of manufacturer.

This compliance is made possible with advanced technology like COPA-DATA’s zenon. The platform supports a wide range of energy protocols, integrating both new and legacy field equipment across the grid — from SCADA control rooms to substation HMIs and gateways. For grid operators, IEC 61850 isn’t just about updating technology; it’s essential for bringing together Distributed Energy Resources (DERs) like solar and wind power with their dedicated communication protocols into the energy grid. This integration is a vital part of the energy systems we will rely on in the future.

Testing for real-world performance

Robust testing frameworks can simulate IEDs, missing IEDs and single signals, enabling operators to pinpoint potential issues, and generate detailed test reports. This proactive testing ensures systems are battle-ready for live grid operations, cutting down on risks and enhancing reliability. This methodology can also save time by automating time-consuming manual tests.

For digital substations, consistency across design, modeling, and implementation is essential. COPA-DATA recommends an integrated approach using computer-aided testing, factory acceptance testing (FAT), and site acceptance testing (SAT). By aligning each stage with a unified vision of resilience, these methods reduce the risk of installation disruptions and ensure each component is prepared to perform.

As the energy sector faces the twin demands of growing power needs and climate action, adopting robust standards like IEC 61850, investing in real-time data systems and prioritizing rigorous testing for digital substations are no longer optional — they’re essential.

Balancing the grid with technology for DERs

The intermittent nature of renewables, like solar and wind, can lead to fluctuations in energy supply, introducing risks of power surges, outages, and inefficiencies. The only way to manage this? Real-time data.

To keep up, utilities need advanced software platforms that give operators real-time visibility into energy generation across the grid. With platforms like zenon, operators get real-time insights, predictive analytics, and the ability to make on-the-fly adjustments. This capability to proactively manage DER variability is critical for delivering consistent, reliable power.
