Digital revolution in transformer substations
As the energy sector continues to evolve, this digital transformation of transformer substations represents a crucial step towards developing grids that are fit for the future, capable of handling the complexities of renewable energy integration, and meeting the changing demands of consumers.

German distribution grid operators are facing a significant challenge as they prepare their infrastructure for the energy transition. By 2030, the goal is to generate 80% of electricity from renewable sources. To meet this ambitious target, naturenergie netze GmbH, a southern German distribution grid operator, has launched a pioneering pilot project to modernise transformer substations more quickly and efficiently.
The project involves creating a digital twin of transformer substations, which serves as a virtual representation of both the primary technology (live components) and secondary technology (control level). This digital twin forms the basis for planning and configuring the conversion of existing substations, such as the one in Rheinfelden.
Key aspects of this digital revolution include:
1. Collaboration between software suppliers Eplan and entegra to combine primary and secondary technology in a single model.
2. Use of 3D scanning and automated data transfer between different software systems to create a comprehensive digital twin.
3. Implementation of the “single source of truth” principle to prevent problematic data redundancies.
4. Standardisation of secondary technology planning using Eplan Electric P8 and Eplan Pro Panel software solutions.
5. Application of lessons learned from mechanical engineering to drive standardisation in the electricity industry.
The benefits of this approach are significant:
– Considerable time savings during the conversion of transformer substations
– Improved efficiency in planning and implementation
– Enhanced ability to adapt to the increasing demand for electricity and flexibility in energy sources and flows
– Better preparedness for the challenges posed by decentralised energy generation and changing consumption patterns
This digital revolution is not limited to naturenergie netze. The open sharing of information among grid operators means that many others can benefit from this innovative approach to planning and implementing conversion and new-build projects more rapidly.
