High Voltage Lab
The main task of the high voltage laboratory is to deliver a platform which enables investigations of power components and subsystems under high voltage and high current conditions as part of the PowerLabDK concept. Focus is on component performance in interaction with complex electric energy systems and with other environmental factors, hereby meeting the needs for power systems based on renewable energy systems.
Modeling
The exposure of components in the future power system requires far more detailed knowledge to their characteristics than the traditional 50 Hz approach suitable for load flow calculations. Broad band models have to be developed for implementation in future grid models.
- Design
Research and development of electrical technologies for design optimization of power components.
- Testing
Experimental investigations on power components for with respect to performance, reliability and broad band modeling. Tests are carried out on models and full size components with advanced test technologies for online and offline use. This includes diagnostic measurement systems for condition assessment of power components.
Main components to be mentioned are transformers, cables, breakers, rotating machines, insulators, power electronics, wind turbine components and more complex subsystems at all voltage levels.
