Outline of Final Research Achievements

Large quantities of electric energy are consumed by induction motor loads. Therefore, improvement of control methods for these motors is very effective to raise energy utilization efficiency. To investigate new control methods in the conditions similar to those of a real power system, electromagnetic transient (EMT) analysis in three-phase instantaneous values is very useful.
In this study, a new squirrel-cage induction machine model with high calculation stability and accuracy for power system EMT analysis has been developed for the purpose of improvement of energy utilization efficiency. The noteworthy feature of the model is in the calculation procedure using a two-stage diagonally implicit Runge-Kutta (2S-DIRK) method and second- order Runge-Kutta method (RK2) without any prediction or delay. Stability, accuracy, and usefulness of the model were confirmed through experiments and numerical simulations.
