This paper develops a three-blade horizontal axis tidal turbine numerical model to determine its influential parameters. First, a tidal turbine simulation model equivalent to Ben-Eschenburg model is built in order to define its physical characteristics including produced mechanical power, load currents and stator voltages of the generator in the Prank frame. Second, sensitivity analysis FAST method is used to determine the influential parameters on the turbine and generator models. The designed tidal turbine numerical model displays qualitative results. In Prank frame, sensitivity analysis results show that gradually tidal currents speed, stator resistance and angular velocity have high influence on turbine power, voltage along d axis and voltage along q axis, respectively.
