Dynamic analysis of a grid-connected induction generator driven by a wave-energy turbine

This paper presents a methodology for predicting instantaneous values of electrical quantities such as active power, reactive power, power factor, current, torque and slip of the grid-connected induction generator driven by a Wells turbine from given data of axial air flow velocity variations with time so that the quality of power fed to the grid can be predicted. An index of power quality could be the ratio of peak active power to average active power. The paper then establishes the effect of taking the electrical transients into account or omitting the same on the accuracy of the modelling for such dynamic studies.
