Abstract: The purpose of the present invention is to provide an alarm setting method for a wind turbine condition monitoring system to monitor the conditions of a wind turbine and notify a manager of abnormalities for enabling the manager to take care of the wind turbine before mortality failure or damage occurs. The alarm setting method for a wind turbine condition monitoring system according to the present invention eliminates difficulties in signal flow and data handling by using vibrational signals for predicting damage and abnormalities; has a detailed setting method; and has excellent predictive validity for failure. [Reference numerals] (AA) Wind speed range setting step (S10) for setting two or more wind speed ranges (W W_1,W_2 ···) in a control part (20);(S20) Vibration signal obtaining step for obtaining vibration signals for one point of a wind turbine and for one point of the components of the wind turbine using an accelerometer (10);(S30) Vibration level computing step for computing the vibration level of the vibration signals obtained in the vibration signal obtaining step (S20) by a unit time (Δt) using a computing part (25);(S40) Determining and data storing step for storing the effective vibration level data (D_e(t)) of the vibration signals obtained when the control part (20) is in a single wind speed range for a setting time duration (D1) in a data saving part (40);(S50) Reference value setting step for setting alarm reference values (S) by wind speed ranges using the effective vibration level data (D_e(t)) of the vibration signals stored in the data saving part (40) and obtained when the control part (20) is in a single wind speed range for a setting time duration (D1);(S60) Alarm signal producing step for outputting alarm signals for a manager by comparing the vibration level (V_r) of the vibration signals obtained when the control part (20) is in a single wind speed range with the alarm reference values (S) in the wind speed range
