Abstract

Based on the ocean model SWAN, the validation results suggested that the model can effectively represent the wave energy characterization in this region. The sea area of Guangdong East Offshore Wind Power Base was selected to focus on the wave energy inter-annual variation and directional distribution, and to explore the significant wave height and mean period characteristics of wind waves and swell waves in all seasons. The results show that the wave energy resource in the study area show a decreasing trend from southeast to northwest with strong seasonal variability. The power density is more than 6 kW/m in most of the sea area in winter and fall, and more than 2 kW/m in spring and summer. The average period in winter is between 5.5-7.0 s in most of the study area, and mostly lower than 6.0 s in summer, which is the smallest. Guangdong East offshore wind power base is mainly in E-NE wave direction throughout the year, and the average effective wave height value is small in May, June and September, with the median and average value in the range of 0.7-0.9 m. and the energy period is the smallest in May-June, with an average value of about 5.1 s. In addition, the waves in this area are dominated by wind waves in winter and swell waves in summer, and the average period swell waves are about 3.0 s higher than wind waves in all seasons.
