Testing, Prequalification and Certification

of Power Converters up to 6 MW

The demand for new power converter applications and product generations is rapidly increasing. To ensure compliance with current and future grid codes, we provide comprehensive testing and pre-qualification services.

In our state-of-the-art laboratories, we simulate and test your systems. Furthermore, we develop generic models that serve as the basis for analyses and simulations. We use these models to evaluate the stability of your system and test its ability to form grids in accordance with the latest system stability roadmap.

We consider both current requirements and future challenges to ensure that your systems remain reliable and powerful in the long term. With our expertise, we accompany you on the path to successful prequalification – for secure, stable, and future-oriented system integration.

Creation of generic models

Development and
optimization

We create precise generic models of your systems and optimize them to provide a realistic representation of their behavior under various operating conditions.

Analysis and validation

We perform detailed analyses and validate the models using real data to ensure maximum precision and reliability.

Simulation and
scenario development

We use the models to simulate various operating and fault scenarios. This gives you valuable insights into the behavior of your systems and enables you to identify and eliminate potential risks at an early stage.

Compliance tests in accordance with standards

We test your system's performance under realistic conditions, including grid fluctuations and disturbances, and evaluate its ability to actively support system stability.

Extensive Testing of your Prototype or Product

We proactively test your system to make sure it will also fulfill future requirements, taking into account future developments and regulations.

Documentation and
Certification

We prepare detailed test reports and assist you with the certification of your systems – an important step for market approval and long-term operation.

Evaluation of system stability and grid-forming properties

Dynamic
stability analyses

We comprehensively check your system for compliance with all applicable connection guidelines and technical standards, including regional and international requirements.

Evaluation of grid-forming functions

We analyze whether and to what extent your system fulfills grid-forming properties and identify potential for optimization.

Long-term scenarios and stress tests

We use special simulations and stress tests to examine the performance of your system across various operating conditions in order to ensure its reliability and efficiency in grid building.
