The invention discloses a transient control method for controlling the synchronous stability of a virtual synchronous control inverter. At present, the research on the stability of an inverter mainly focuses on the small-disturbance stability of an inverter in a micro grid. There is relatively less research on the transient stability under large disturbance, and the stability mechanism is unclear. In view of the virtual power angle instability caused by inverter current saturation, reactive power plus transient control are introduced into virtual synchronous control, so that an inverter has a reachable stable equilibrium point in the transient process of current saturation, and the synchronous stability of the inverter under large disturbance is ensured. The technical problem that there may be no stable equilibrium point in the transient process for the system due to saturation of the inner current loop of an inverter is solved. Transient instability of virtual power angle after an inverter goes to a current source mode is prevented.
