Simulation of Imitation of the Characteristics of Wind Turbine Based on DC Motor with Matlab
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.

I. INTRODUCTION
The initial investigation and research conducted in the
laboratory could actively enhance the development of
wind power technology. Because of the limited conditions,
there is no wind turbine or wind farm in most laboratories,
which leads to great difficulties for the laboratory research of
wind power technology. Consequently, it is great important to
explore the ways to imitate wind turbine characteristics for indepth
study of wind power technology in the laboratory. It is
important for the promotion of experimental wind turbine
technology and applications [1-8]. It can also bring significant
economic and social benefits.
In recent years, with wind power technology having gained
fast development, many advanced technologies proposed from
the laboratory, such as variable blade control, variable speed
constant frequency (VSCF) generation, direct –drive without
gear box have been applied to actual spots[12]. A double-fed
induction generator (DFIG) as a load connects with a direct
current motor (DC motor), which imitates the wind turbine [4].
However, imitation of the characteristics of the wind turbine
was not discussed in detail. Although the rough control
strategy, hardware platform and monitor software for the wind
turbine imitation system were created [1], the results of
imitation can’t clearly illuminate that the direct current motor
simulating wind turbine is feasible.
