The invention discloses a transient stability analysis method for new energy access to a power grid in a planning stage, belongs to the technical field of power grid transient stability analysis, and can solve the problems that the technology cannot be combined with a new energy access position for evaluation and analysis, and the evaluation accuracy and reliability are low. The method comprises the following steps: S1, according to working parameters of a power grid and a plurality of new energy stations, constructing an operation model of the power grid, and obtaining first admittance information of power grid nodes after the plurality of new energy stations are connected to the power grid; s2, according to the fault factor and the operation model of the power grid, obtaining instability power angle information of a generator set in the power grid when transient instability occurs in the power grid under different working conditions after the plurality of new energy stations are connected to the power grid,
