The invention provides a real-time emergency control method of a power grid, and belongs to the field of electric power systems. According to the real-time emergency control method of the power grid, influences, caused due to the fact that an initial rotor angle is too large, on critical cluster recognition are overcome, and critical clusters can be recognized more accurately; the defect that in former steady state analysis, equivalent calculation must be conducted is overcome, stability judgment of a whole system is conducted through several generator units in the critical clusters, therefore, the calculation amount is saved, and system stability judgment can be completed more rapidly. According to the real-time emergency control method of the power grid, derivation of the generator tripping amount is conducted through equivalent calculation of the critical clusters and residue clusters; on the basis of a synchronous phasor measuring unit (PMU), the method can supplement a traditional ...
