The utility model relates to a reactive power automatic compensating mechanism of wind generator; a circuit mutual inductor (3) and an air switch (4) are connected with a wind generator voltage output terminal (1), an arrester (6), a fuse (7) and three sets of three-phase combination switch (8) are successively arranged on the air switch (4) connected with the output terminal; the three-phase combination switch is connected with a compensation capacitor unit (2) and a switching light (10); a controller (5) is connected with an attached compensation capacitor unit of the wind generator (2), a current transformation (3) and the three-phase combination switch (8) respectively; the controller (5) is connected with a key switch (11) which is positioned at the primary of a transformers (12) (13). The utility model can avoid the problem that the generator is cancelled because of low system voltage.
