Abstract :
The paper compares different solutions able to mitigate the effects on the electric grid of active power holes caused by the ITER Neutral Beam Injector (NBI) load: when, during the NBI operation, a breakdown of the accelerator grids occurs, the main power supplies have to be shut down and then, within 130 ms, switched on again. To overcome the consequent power steps, different schemes based on energy storage devices have been evaluated and compared in the paper. One particular solution is analyzed with the help of numerical simulations.
