The Electrical PTO-Lab is a turbine emulator to reproduce the mechanical output of an ocean energy device/wind turbine
It consists of a HIL (Hardware in the Loop) test bench for grid connection of wind turbines and ocean energy converters, focused on testing electrical components
(electrical generators and/or power converters). This test bench simulates the power production of a device with a rotary movement and it can be divided into three key elements: Device Emulator, Electrical Generator and Power Converter.
Services currently offered by the infrastructure:
• Mathematical Model validation.
• WEC Control: tuning of controllers, optimum efficiency control, peak to average power control.
• Grid connection control: Interaction between components in an electrical power network in various grid conditions, as strong grid, weak grid and island operation; Investigation of component behaviour during abnormal operation conditions, transient behaviour; Behaviour of converter control system in non- ideal network conditions, as weak grids and island operating modes, transient events, dips and circuit breaker operations etc.
• Final software testing.
• Electrical component testing.
The test rig has been used in the following projects:
• Development of turbine and generator control algorithms for small scale wind turbines.
• Development of wind turbine grid connection control algorithms and test under distorted grid conditions, including voltage sags, frequency variations and harmonics.
• Small scale test for multi MW wind turbines.
• Simulate the behaviour, adjust the drive parameters and test some parts of the control software of an oscillating water column
