| Abstract |
The paper presents different control strategies of the crowbar protection when a variable speed wind turbine based on a doubly fed induction machine is generating electrical energy during a voltage dip in the grid.The proposed control strategies provide the wind generator with the capacity for don’t disconnect from the grid while a voltage dip occurs, and return to the normal operation conditions. This will be achieved by a protection circuit called crowbar.In addition, complementary control algorithms for flux damping and voltage recovery will be proposed.Finally, the presented control strategies will be validated in simulation for a 1700KW generator. |
