Abstract

In 2016, Korea started to develop a 30kW class wave power plant connected to a breakwater. After designing, manufacturing and performance testing of each energy conversion device, a demonstration plant was installed in Mukri Port, Jeju Island, Korea in 2021. After passing the completion inspection of the power generation facility, a full-scale grid-connected trial operation began in October 2021. The power plant consists of a sloped Oscillating Water Column, impulse air turbine, permanent magnet synchronous generator, AC-DC converter, energy storage system and integrated control system. This study introduces the performance evaluation results based on real sea operation data. The performance evaluation of the wave power plant under various wave height and period conditions was performed to evaluate the output power and efficiency of each bin. In addition, performance evaluations were conducted according to wave direction and tidal conditions to examine the effects. The correlation coefficient was derived by analyzing the correlation between wave height, period, wave directions, tide level and output power.

30kW级带防波堤的OWC波浪电站性能评价

2016年，韩国开始开发与防波堤相连的30千瓦级波浪发电站。经过各能源转换装置的设计、制造和性能测试，于2021年在韩国济州岛木里港建立了示范工厂。发电设施竣工验收合格后，于2021年10月开始全面并网试运行。该电站由倾斜振荡水柱、冲击式空气透平、永磁同步发电机、交直流变换器、储能系统和综合控制系统组成。介绍了基于实际海上作业数据的性能评价结果。对波浪动力装置在不同波高和周期条件下的性能进行了评价，评价了各仓的输出功率和效率。此外，还根据波浪方向和潮汐情况进行了性能评价，以检验效果。通过分析浪高、周期、波浪方向、潮位与输出功率的相关关系，推导出相关系数。
