LORC tests and demonstrates technology for harvesting renewable energy offshore

Latest News

Meeting industry’s needs for environmental testing of large components for offshore use is now one step closer with the ordering of a climatic chamber for a new LORC test centre.

Grid Simulation

Both test docks of LORC Nacelle Testing will be supplied from a shared electrical system allowing either a fixed medium voltage supply at 33kV (50Hz) or a converter-based artificial grid supply (0-33kV, 45-65Hz), where both voltage amplitude and frequency can be changed, called a grid simulator. This makes it possible to carry out grid simulator tests according to grid code standards, perform Low Voltage Ride Through (LVRT) and even Temporary Over Voltage (TOV) up to 48kV. Furthermore, the electrical system is prepared for a future upgrade to voltage levels of up to 72 kV.

LNT will modulate a complete wind turbine park and apply the calculated voltage and frequency to the single turbine being tested in the test dock. By doing so, it will be possible to determine how the turbine behaves in a park context and what happens at the output of the entire park during a variety of grid events.
