基于风电场海域海况的波能浮子阵列发电功率优化

  目的  为了响应国家集约用海，发展清洁能源，助力碳中和，对海上风电-波浪能装置多能融合模式进行初步分析，对波能浮子进行优化设计，以获得更高的功率输出。  方法  依据势流理论，对漂浮式风机平台-波能浮子阵列进行仿真计算，分析浮子的外形尺寸和固有周期对浮子的输出功率的影响。  结果  仿真结果表明:同一固有周期下，波能浮子越扁平，波能浮子阵列的总发电功率越大，且浮子的经济性差异很小。对于海况下，不同固有周期的波能浮子阵列经济性差异较大，因此要综合分析考虑。  结论  在已知海域海况条件下，可以通过对波能浮子固有周期和外形尺度进行优化设计，使波能浮子获得更高的功率输出，提高单位海域能量产出。

Power Optimization of Wave Energy Converter (WEC) Arrray Based on Sea Conditions of a Wind Farm

  Introduction  In order to respond to the national initiative of intensive sea use, develop clean energy, and contribute to carbon neutralization, a preliminary analysis was conducted on the multi-energy integration mode of offshore wind power and wave energy devices, and the WEC was optimized to achieve higher power output.   Method  Based on potential flow theory, the floating fan platform - WEC array was simulated to analyze the influence of the dimension and the inherent period of the WEC on the output power of the WEC.   Result  The simulation results show that under the same inherent period, the flatter the WEC is, the greater the total power of the WEC array is, and the economic difference of the WEC is small. For sea conditions, the economic difference of WEC array under different inherent periods is great, so it should be considered comprehensively.   Conclusion  In the known sea conditions, the inherent period and the dimenson of WECs can be optimized to achieve higher power output and increase energy output per unit sea area.
