Claim 3:
4. The method for assessing the short-term voltage stability of the power grid based on the synchronous spatio-temporal information learning according to claim 3, wherein in step S4, when the power grid suffers from the transient fault during the online operation, synchronous phasor measurement units deployed at individual monitoring buses in the power grid acquire the temporal data of responsive trajectories of the voltage V, the current I, the active power P, and the reactive power Q within the L time instants in real time after the power grid suffers from the transient fault, the temporal data of responsive trajectories of the voltage V, the current I, the active power P, and the reactive power Q are input into the short-term voltage stability assessment model that passes the performance test in step S32, and the short-term voltage stability assessment model outputs the online assessment result indicating whether the power grid is in a stable status or an unstable status.
