A Dynamic Wind Turbine Simulator of the Wind Turbine Generator System

Abstract

To study dynamic performances of wind turbine generator system (WTGS), and to determine the control structures in laboratory. The dynamic torque generated by wind turbine (WT) must be simulated. In there paper, a dynamic wind turbine emulator (WTE) is designed, which consider wind shear and tower shadow effect, and a dynamic torque compensation scheme is also developed to compensate the different inertia between a lab scale motor and a actual rotor blade and shaft. The dynamic torque is taken as reference to control an inductance motor which is driven by an inverter to simulate the wind turbine. The simulation results show this simulation system is feasible and efficient. The wind turbine simulator close to actual ones and can be used as a substitute for actual wind turbine in experiment.
