Zusammenfassung:	The invention provides a regional power grid tie line power transmission capability calculation method considering N-1 security constraints. The method comprises the following steps: S1, establishing a transmission capability calculation model considering the N-1 security constraints; wherein after the N-1 security constraint is considered, the tie line power transmission capability represented in the feasible region form is defined as all combinations of ground state tie line power meeting the ground state operation constraint and the N-1 security constraint; S2, based on a tie line power transmission capability calculation method of a decoupling strategy, carrying out decoupling dimension reduction calculation on a feasible region considering massive N-1 fault states; wherein the decoupling characterization strategy comprises the following steps: solving a feasible region meeting the fault constraint of the c-th line and the ground state constraint in parallel; and representing the feasible region consideri
