Vidnovluvana energetika| Summary: | Stand-alone wind turbine systems with induction generator can be used to supply power to remote areas from central system consumer as having a relatively simple design, high reliability, and not complicated scheme connection to work in parallel with the electrical grid. At the same time, the induction generator requires supplying reactive power to stator winding for selfexcitation, which is often supplied from capacitors block.The most difficult task for the performance of wind turbine with induction generator is the regulation of the tension and frequency, which are influenced by the variations of wind speedand keeping the indices of quality of electrical energy within mode operation.The present article analyzes the efficiency and performance of the stand-alone wind turbine system with induction generator and pulse converter for charging battery system throughsimulation model. The model was developed with software Matlab/Simulink program. Found that adjusting the duty cycle signal between 0.1 up to 0.9 is possible to use the maximum wind energy, which is transformed by the induction generator. |
