Özet:

 

A small scale experiment wind energy kit is prepared in order to  introduce renewable energy applications.  The kit consists of a wind  turbine with horizontal axis, a direct current (dc) motor as generator  and variable wind excitation system.  Performance characteristics of  the wind system are defined for different wind speeds.  It is found  that at the highest 10 m/s wind excitation, the maximum turbine  mechanical power from wind is about 0.30 W at 5.3 V., maximum output  power of the generator is about 0.18 W and maximum electrical  efficiency is about 7% at 4.27 V., wind turbine power coefficients  Cp are 12.53% under maximum turbine mechanical power, 12.06  % under maximum electrical efficiency cases.  Also mechanical  frictional losses of system are considered and added to analysis.  The  wind kit is also operated with a proton exchange membrane (PEM) type  electrolyser for hydrogen production.  The outputs of generator,  inputs of PEM electrolyser and its rate of hydrogen formation  characteristic are measured and modelled separately.  Overall system  is defined in MATLAB/Simulink.  Operating points of PEM electrolyser  on wind system kit are predicted by modelling.  Relative errors are  about 1-4% for voltage, 0.6-3% for current at 5.7-10 m/s wind  interval.  The rate of hydrogen production of wind generator-PEM  electrolyser system is analyzed with respect to input wind speeds.  The rate of hydrogen formation of the system is 0.4 ml/min at 10 m/s  wind speed.  The system kit has small scale, low performance and  inexpensive tools, but it can be used not only for education but also  for research tests about similar systems.  Approaches in the study can  be applied to systems with larger and special devices to carry out  their performance tests.
