Abstract

With the depletion of fossil fuels and increasing environmental concerns, the development of renewable energy, such as wave energy, has become a critical component of global energy strategies. However, challenges persist in the field testing methodologies for wave energy converters (WECs). In this paper, a numerical wave field of the Dawanshan Island Sea Area in Zhuhai City is constructed based on the MIKE21 SW wave model and by using an NCEP wind field driving model. In conjunction with the IEC-62600-100 standard, by taking site testing of the “Wanshan” wave energy converter on which a sea trial has been conducted in Dawanshan Island of Zhuhai city as an example, research on-site testing method for a wave energy converter has been carried out. The wave measurement position for the “Wanshan” converter was determined by combining statistically analyzed field data with a validated numerical wave model. By comparing a valid wave height at the position where a wave rider is located with a valid wave height at the position where the “Wanshan” wave energy converter is situated, the correlation coefficient between simulation and observed data reached 0.90, with a root-mean-square error of 0.19. The representativeness of wave measurement data during site testing is verified and can be used as a basis for calculating the input energy of the “Wanshan” wave energy converter.
