Accurate modelling of generators plays an important role in power system studies. Inaccuracies in modelling can have a negative impact on the simulation results which can result in inapproapriate decision being taken by the power system planners. Saturation modeling in generator can affect the damping of electromechanical modes. Therefore, it is important that the different available modelling techniques be investigated and their effects on the damping of the electromechanical modes be quantified. In this paper, three different saturation modelling techniques (effective excitation, total, and incremental) are investigated. Simulation results show that the effect of saturation representation on the electromechanical modes (local modes) depends on the saturation modelling technique and the type of control configuration used for the excitation system.

“…From our experience [I], the differences in results are caused mainly by the different modelling approaches with regard to: (1) speed voltage terms, (2) turbine output, and (3) saturation. The impact on electromechanical modes of variations in the first two modelling aspects is reported in [2,3]. However, the effect of variations in modelling saturation has not been well researched.…”

Several industrial-grade power system simulation tools are commercially available in the market. They are expensive to acquire and time-consuming to learn. As a result, very few institutions (utilities, academiclresearch organizations) can afford to use more than one power system simulation tool. The simulation tools differ in their components modelling. Different simulation tools can give different results for the same system model. Understanding the reasons for the discrepancies in the results is not a trivial task. In this paper, we investigate the effect of variations in modelling generator saturation. We carried out an eigenvalue analysis of a single machine infinite bus (SMIB) system using PSSIE, PowerFactory, EUROSTAG, SSAT, and MatNetEig. The simulation results show that the effect of saturation on the local modes is erratic and there is a need for further research on saturation representation in power system stability simulation tools.
