The utility model discloses a wind power farm static reactive compensation generator associated performance detection system, for solving the problem that it is difficult to detect associated performance between wind power farms. The wind power farm static reactive compensation generator associated performance detection system comprises a voltage transformer (4), two reactive generators and a capacitive reactive compensator (11) which are respectively arranged on a 35kV bus (1), wherein an A phase of a secondary side of a low-voltage side current transformer (2) of a main transformer (3) of the wind power farm is electrically connected with a current input terminal of a first detection channel of a power quality on-line monitor (12), an A phase of a secondary side of a current transformer (5) of a first reactive generator is electrically connected with a current input terminal of a second detection channel of the power quality on-line monitor (12), an A phase of a secondary side of a current transformer (7) of a second reactive generator is electrically connected with an input terminal of a third detection channel of the power quality on-line monitor (12), so as to detect the associated performance level between the two sets of reactive generators.
