Abstract :
Wind power generation systems influence power quality in a very specific manner creating the requirements for detailed and correct analysis of disturbances caused by wind generators. Wind power system cause sub- and interharmonic disturbances within the spectrum of voltages and currents. The paper shows alternative method of spectrum estimation in power systems, tested on the system with the doubly fed induction generator (DFIG) connected to low voltage distribution grid. Advanced spectral estimation algorithm (ESPRIT) are applied to overcome the drawbacks of Fourier-based techniques.
