Abstract -- In order to demonstrate the wind turbine in the
laboratory, this paper first analyzed the operation principles, the
power and torque characteristics of the wind turbine and direct
current (DC) motor, then it investigated the operation
characteristics of the wind turbine in contrast to those of the DC
motor. The torque imitation scheme was provided, which imitates
the torque characteristics of wind turbine by controlling the
armature current of DC motor. The scheme has good
performance and high feasibility. At last, the simulation of wind
turbine operation characteristics was performed, the simulation
was done under two typical conditions of variable wind speed
and variable machine rotational velocity. The characteristics
curves are presented in the paper. The simulation curves are
highly consistent with theoretical datum. The torque imitation
scheme of wind turbine characteristics can be conveniently used
in the study of wind power generation in the laboratory.
