The invention discloses a method for online calculating the number of repeated overhaul times of the same fault of a fan based on defect lists, and the method comprises the following steps: 1) collecting the defect lists created on the same day of a statistical day T0 from a wind field production management system, and forming a set A0; 2) rejecting defect lists of which the states are temporary storage, canceling and discarding states from the set A0 to form a set A; 3) from the n defects of the set A, taking a defect fan ID + equipment KKS + defect phenomenon as a main key; 4) querying defect sheets with the same main key in a statistical time range from a wind field production management system by using the query main key Ki of each defect, and forming a defect sheet set Bi; 5) rejecting the defect sheets with the states of temporary storage, canceling and discarding from the defect sheet set Bi to form a set Ci; 6) enabling the number mi of the defects in the set Ci to be the number of times of repeated overhaul of the fan and the fault corresponding to the query main key Ki; and 7) returning to the step (4), continuing to calculate the repeated overhaul times of other fans and faults by taking Ki + 1 as a query main key until i + 1 is equal to n, and obtaining the number of times of repeated overhaul of the same fault in the statistical time range of the fan subjected to daily fault overhaul. The scientific and rapid index obtaining method is provided for a production management department.
