Abstract
This paper deals with a conversion system concept based on the real time simulation of a hybrid offshore wind and tidal current system. In order to provide reliable, environmental, and costeffective electrical energy we present a simulation research device composed by two real time emulators:, one for each type of energy: a wind turbine emulator and a tidal turbine emulator. The wind turbine emulator based on a permanent magnet synchronous machine, is used to simulate the characteristics of a working turbine and an electrical generator. The tidal turbine emulator has in its composition 3 electrical drives: an asynchronous drive with vector control used to simulate the behaviour of a tidal turbine, a double feed asynchronous generator and an active break. Both of them are using the “hardware-in the-loop” techniques.
