description | A wave
energy converter (WEC) based on a direct mechanical drive system (DMDS)
exhibits limited performance when the sea state stands for a short period. This
study aims to increase the efficiency of a WEC-DMDS mechanical system applied
under short-wave conditions. A novel WEC is designed by applying cascaded gear
and reducing the flywheel inertia to achieve better efficiency in a short-wave
period. By applying a short-wave period of less than 2.84 s for the actual
scale, the UCG-WEC can produce a CWR of 18.5%, mechanical efficiency of 87%,
and a maximum power of 200 W. These values are much better than those obtained
previously, where zero efficiencies were achieved for the same wave period
range. In addition, this model performs well under both high-and low-wave
steepness conditions. This study also evaluates variations in lever length and
effective height. The C-type configuration, with a relative length ratio of
0.74, is found to be the optimal choice. |
