The present invention relates to the field of motor control and electric power system new energy generation technology, especially to a brushless doubly-fed motor virtual synchronization control multi-scale modeling method. The method comprises the following steps of: S1: establishing a brushless doubly-fed motor transient model according to special physical structures and electrical features of abrushless doubly-fed motor; S2: combining the brushless doubly-fed motor transient model and a virtual synchronization control algorithm, and establishing a brushless doubly-fed motor single virtualsynchronization control model; S3: calculating a complete mathematical model of the brushless doubly-fed motor single virtual synchronization control model according to the features of the brushless doubly-fed motor single virtual synchronization control model; and S4: forming virtual synchronization models with different time scales after the single virtual synchronization control model is combined with devices or systems with different time scales. The brushless doubly-fed motor virtual synchronization control multi-scale modeling method can solve the problem that a current brushless doubly-fed motor control model influences a control effect and precision, can allow the model to match scales of systems and can improve a system control effect.
