ABSTRACT
The call for reliable, consistent and efficient
power supply in all sectors of the economy in Nigeria especially in Agriculture
has led to the emergence of cheap, reliable, pollution free source of power,
which is the wind turbine system. This
paper compared the bahaviour of a single generator in a doubly fed induction
generator (DFIG) and parallel connected generator in a DFIG wind turbine
system. Dynamic characteristics such as the stator current, power output, and
efficiency of both systems were studied and computer simulations of the
proposed model carried out using MATLAB/SIMULINK. A mathematical model was
developed to enable MATLAB/SIMULINK simulate the two generators in parallel;
the conditions for connecting generators in parallel were also considered for
proper simulation of the parallel system. It was observed that a better
efficiency of about 83% was obtained when two generators were synchronized as
compared to that of 64% for the standalone generator in the DFIG after machine
loses were assumed thereby giving a better power output.
Keywords: Doubly fed induction generator (DFIG), DQ reference frame, Standalone generator, Parallel generator, MATLAB/SIMULINK
