采用潮流流速区间精细化划分法、对比分析法等方法
分析潮流采样时间间隔所导致的测试海域潮流能资源评估结果之间的差异性
研究潮流采样时间间隔对潮流能发电装置输出功率、转换效率、年发电量等指标的影响。结果表明:当潮流采样时间间隔为5 min或10 min时
对于评估测试海域潮流流速的分布频率无显著差异
但是随着潮流采样时间间隔的继续增大
所获取的现场测试数据无法精细刻画测试海域潮流流速的分布情况;应用潮流采样时间间隔为5 min或10 min的现场测试数据
评估潮流能发电装置的开始发电时的流速值、输出功率的最大值和最小值、转换效率的最大值等指标时无差异
评估潮流能发电装置转换效率的最小值和年发电量的计算结果时差异性较小
具体数值相差分别为0.6%和0.26%。
This paper uses mathematical methods such as the refined division method of tidal current velocity interval and the comparative analysis method to analyze the differences between the evaluation results of tidal current energy resources in the test area caused by the tidal current sampling time interval
and studies the impact of the tidal current sampling time interval on the output power
conversion efficiency
annual power generation and other indicators of tidal energy converters. The results show that when the tidal current sampling time interval is 5 min or 10 min
there is no significant difference in the distribution frequency of tidal current velocity in the test area
but with the continuous increase of tidal current sampling time interval
the obtained field test data can't accurately characterize the distribution of tidal current velocity in the test area; Using the field test data with the power flow sampling interval of 5 min or 10 min
there is no difference in the evaluation of the cut in velocity
maximum and minimum output power
and maximum conversion efficiency of the tested tidal energy converter. The difference between the minimum conversion efficiency and the annual power generation of the tested tidal energy converter is also small
with the difference of 0.6% and 0.26% respectively.
