“…Transient performance is one of the key interests of machine performance and time constant regulators (TCRs) for these micromachines have been created to extend the usefulness of micromachines to accurately simulate transient and dynamic behaviour of practical machines [22]- [24]. They have been used to simulate turbine generators [25], create generator models [26], determine generator parameters [27]- [29] and validate digital models of electric power systems [30]. They have been used to study generator stability and for the digital control of generators [31]- [34].…”

Wind power installations are on the increase, globally and in South Africa. Several research areas are affected by this uptake of wind energy systems, which include wind generator performance and power system stability studies. Dimensional analysis is a very powerful tool. It allows machines and systems to be down-scaled in order to get a preliminary result before constructing a prototype by establishing laws of similitude between the original and its model. Studies using micromachines, a more accurate means of generator simulation, can be used to investigate issues of grid integration and dynamic performance of wind systems. Scaling methodologies are reviewed for use of the techniques for developing micromachines for wind generators.

“…In power system dynamic studies, the synchronous generator is commonly represented using the dqaxis. In the last few decades, various saturation models have been proposed with different degree of complexity [4]- [10]. However, up to now there is no an agreed modelling technique that should be used for saturation modeling [11].…”

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.
