A power electronic device control initialization method, comprising: (1) before a target control strategy starts up, measuring the electric quantity from an actual system to carry out state acquisition, collecting real-time electric quantity data, and obtaining setting value information required by a control loop; (2) according to the setting value information required by the control loop in step (1), setting an initial value of an integrator in the control loop, and locking the initial value of the integrator before starting up control; and (3) setting a target control strategy reference value as an electric quantity measurement value obtained in step (1); and a control system sends a control start signal to a modulation and valve group control to start the control strategy. By means of setting the initial value of the integrator in the control system and controlling a target reference value when the control strategy is initialized, the method can reduce circuit impact, improve the rapidity and stability with which the power electronic device controls during start-up, and provide more application scenarios for the power electronic device. The method can be widely applied in the field of power electronics.
