Abstract :
This paper represents a new model of the Variable Frequency Transformer (VFT) using MATLAB/SIMULINK. The VFT is used to connect two power systems. The simulations shown in the paper accurately represents the VFT´s dynamic characteristics. Based on this model, some further simulations are conducted to study VFT´s characteristics under fault conditions and its roles in preventing the spread of faults into the other area. The simulation results show that the VFT effectively suppresses the power oscillations between the two interconnected power systems and thus prevents the faults from spreading.
