Power electronic equipment control initialization method

The invention provides a power electronic equipment control initialization method, which comprises the following steps of: (1) before a target control strategy is started, measuring electrical quantity from an actual system to obtain a state, and collecting real-time electrical quantity data to obtain setting value information required by a control loop; (2) realizing integrator initial value setting in the control loop according to setting value information required by the control loop in the step (1), and locking an integrator initial value before starting control; and (3) setting a target control strategy reference value as the electrical quantity measurement value obtained in the step (1), sending a control starting signal to modulation and valve group control by the control system, and starting a control strategy. When the control strategy is initialized, the circuit impact is reduced by setting the initial value of the integrator in the control system and the control target reference value, the rapidity
