A dynamometer set up for simulation of a wave energy operated Wells turbine

The present trend in the world is to go for ecologically friendly methods of power generation. In this paper a dynamometer set up simulating a wave energy driven Wells turbine with proper scaling is proposed. This is a new dynamic drive test set up for evaluation of alternative generator configurations. Open loop and closed loop (P, PI and PLL controllers with speed and current feedback) studies are carried out on the set up. The references used as input in the closed loop simulations, vary dynamically as the data recorded at the site. The behaviour of a typical wave energy operated Wells turbine is studied and simulations are also carried out with axial velocity given as input. Both steady state and d-q theory approaches are used for the modelling of the load induction generator feeding power to the grid
