“…This methodology has been developed over the years [25], [26], [27], [28], [29], [30], [31], [32] and has been applied much more often than testing methods based on frequency scans. Frequency scans are still quite useful, particularly for the determination of the linear characteristics of control functions such as power system stabilizers.…”

This paper focuses on a few different aspects of the dynamic model validation process. It briefly describes the undergoing development of NERC standards that would require the validation and periodic re-validation of dynamic simulation models and then discusses the capabilities and shortfalls of the different approaches that might be applied to comply with such requirements. Finally, the paper presents some brief examples describing the use of such models in system simulations and how these results could affect the technical and economical operation of power plants.

The paper introduces the so-called hybrid state model of a synchronous machine based on the superposition principle of the two-port representation of d-axis (two-port circuits) and the single-port structure of q-axis equivalent circuits. The detailed formulation of the hybrid state model is developed in terms of the equivalent-circuit parameters of the machine. Analytical expressions of terminal voltages and the field current following the decrement tests are derived. A practical application of the model for the load rejection test analysis is investigated. Comparisons are made between simulation results and actual data obtained from a laboratory machine to assess the efficacy of the proposed synchronous generator framework analysis.
