The temperature rise test of 3.4 MW double-fed wind turbine is carried out by reducing the current load method.The results show that the motor temperature rise obtained by reducing the current load method is in good agreement with the motor temperature rise under the full power test,and the error is only about 1 K.This method can be used in the test station with small capacity to test the high power motor,and has important practical significance for the motor test equipment with insufficient capacity or without full power test conditions.
