Behaviour of Doubly-Fed Induction Generators during Grid Faults and the Impact on a Distance Relay KU Leuven
Since the evolution to big scale wind power plants, wind turbines are also coupled to the transmission grid instead of the distribution grid, causing new protection problems. Problems arise as the short-circuit behavior of wind turbines equipped with doubly-fed induction generators (DFIG) differs fundamentally from traditional power plants equipped with synchronous generators. When applying a three phase short-circuit at the terminals of the ...
