Method for calculating strong excitation capability of stator winding of superconducting phase modifier

The invention relates to a method for calculating the strong excitation capability of a stator winding of a superconducting phase modifier, and the method comprises the steps: inputting various parameters of the stator winding, stator cooling water parameters, and stator and stator cooling water material attribute parameters; the stator winding loss under the rated working condition, the stator winding heating power during forced excitation, the water-cooling stator winding water outlet stable temperature before forced excitation, the final steady-state stator winding water outlet temperature if forced excitation current continuously exists, and the water-cooling stator winding temperature rising time constant in the forced excitation process are calculated in sequence; and the duration time allowed by the allowable limit temperature rise of the winding is reached under the strong excitation overcurrent, and the duration time represents the strong excitation capability of the stator winding of the superconduc
