Abstract

In the field testing of power characteristics of wave energy converter, the calculation of wave input energy is an important work. Based on the analysis of wave energy flux calculation methods at home and abroad, the wave energy flux calculation methods proposed by the International Electrotechnical Commission（IEC） and the European Marine Energy Center（EMEC） are studied, and the two wave energy flux calculation methods are compared and analyzed by using the field testing data. The results show that the wave energy flux calculated by the method proposed by the IEC is greater than that proposed by the EMEC, and about 52.1% of the field testing data is different between 20% and 30%, but there is a strong linear positive correlation between them. The conversion efficiency of wave energy converter calculated by the method proposed by the IEC is less than that proposed by the EMEC, and the reason why the difference of conversion efficiency is the same as that of wave energy flow is analyzed theoretically. The research results provide a reference for the calculation of wave input energy in the field testing of wave energy converter.
