| Abstract: | Different operating conditions of wind farm impose new challenges on the setting of protection relay.Short-circuit characteristic is the basis of relay protections.The mathematical model and electro-magnetic transients of a doubly fed induction generator(DFIG) are discussed.The setting of protection relay and the sequence current model of wind farm are established when fault is present in the grid connection line.The main factors that influence the short-circuit characteristic of wind farm and the relay set... |
