    It is aimed to develop the wave energy sector with the Open Sea Operating Experience to Reduce Wave Energy Cost (OPERA) funded by the European Union. Energy quality in wave energies is evaluated with the electrical power quality standards prepared by the International Electrotechnical Commission (IEC) for marine energy converters. Harmonic distortions (harmonics and telharmonic) are determined according to the analysis methods given in this standard. Analysis of harmonic distortions is evaluated in three parts: harmonic distortions, interharmonic distortions and high frequency harmonic distortions. Analysis and observations are analyzed based on Fast Fourier Transform (FFT) [162] . With appropriate filtering techniques (active and passive harmonic filters), the harmonics causing the problem are attenuated or eliminated.
