Abstract：An improved time-domain online dynamic equivalent method is presented, which is suitable to shipboard power system. It preserves the structure of the generator, excitation system and governor system. Sixth-order generator equation is used to reduce the grid considering the subtransient.Formulas and the aggregation steps are come out. The time-domain non-iterative algebraic operations process is used to calculate equivalent parameters. For verifying the effect of this aggregation method, the method is applied to reduce a twelve generators shipboard power system. The equivalent parameters and the dynamic response curves are presented in PSCAD/EMTDC simulation environment.And the simulation curves show that the equivalent system retains the dynamic performance of the original system with good accuracy.
