This paper describes an algorithm to calculate low-order linear models of power systems from small-signal time-domain simulation data. The linear system models preserve the modal characteristics of the underlying power system. The method is based on the computation of a real symmetric matrix and is well suited for the analysis of large data sets. The results presented in the paper include the computation of a transfer function suitable for power system stabilizer design and the synthesis of an equivalent linear system from a three-phase power system model
