The invention discloses an adaptive splitting control method. The method comprises the following steps that: when a power grid malfunctions, and an on-line monitoring system is unstable, it is determined that the power grid needs splitting; an electromagnetic looped network is determined according to a breadth-first search algorithm; the splitting mode of the electromagnetic looped network is determined according to the electromagnetic looped network; splitting is performed on the splitting mode according to the preset time and sequence of switching; and emergency measures are taken for islands obtained after splitting so as to ensure the stable operation of the islands. According to the method of the invention, the constraint conditions of the electromagnetic looped network are fully considered, and therefore, existing adaptive splitting control can be improved, and the safety and stability of the power grid can be improved.
