Abstract:

By using the observed wave data from September 2006 to August 2011, the wave energy resource was analyzed. In order to analyze the wave energy resources reasonably, the value of wave energy density, frequency of effective SWH (Significant Wave Height) and wave energy storage were exhibited. Results show that: 1) Wave energy density in most of Taiwan Island waters is above 3 kW/m, areas with relative high values are located in Keelung, Penghu, Hualian, surrounding waters of Dawu, especially Dawu waters, even up to 7.15 kW/m. Wave energy density in January and October is much larger than that in April and July. 2) Wave period in west waters of Taiwan Island is 4.5-5.5 s, about 6.0 s in east waters of Taiwan, Keelung waters and Eluanbi waters. 3) Frequency of effective SWH is large totally, and the frequency in January and October is much larger than that in April and July. 4) Wave energy storage around Taiwan Island waters is above 2×104 kWh·m-1. 5) Rich areas of wave energy around Taiwan Island waters are mainly located in Keelung waters, Hualian waters, Dawu area and Penghu waters, and indigent area is Kaohsiung waters.

Key words: Taiwan waters, wave energy resources, wave power generation, wave energy density, effective SWH, wave energy storage
