The invention discloses a method and a system for generating a strategy for suppressing short-circuit current based on multiple limiters. The method comprises the following steps: when III-type measures exist, calculating a III-type branch column admittance array according to the position of a branch to which limiting impedance is added; constructing a control participation matrix of a class III limiter according to the class III branch column admittance array; performing matrix Hamden product on the control participation matrix and the III-class branch column admittance matrix to generate a III-class admittance additional matrix after the network structure is transformed by the impedor; when the I-type or II-type measures do not exist, generating a calculation matrix cluster containing all the measures of the limiter according to row elements in the III-type admittance appending matrix; forming a compound control admittance calculation matrix cluster considering the class II and the class III when the class
