潮流能发电装置性能综合评估方法研究

The study of the integrated evaluation methods of tidal current energy generating device

目前,我国还没有建成为潮流能发电装置提供试验、测试与评估的海上测试场。潮流能发电装置性能综合评估方法的研究是海上测试场建设理论研究的重要组成部分,为改进潮流能发电装置的性能提供可靠依据。文章在模糊综合评判模型的基础上利用灰色关联理论修正主观权重,分析了潮流能发电装置性能各项指标,给出装置性能评估的层次模型。通过对原始指标数据的标准化处理,使指标数值均处于(0,1)内,降低了计算的复杂度;利用变异系数和关联度修正初始权重,得到潮流能装置多指标的综合权重量化值以及最终评估结果。该方法简化了标准层次分析法中一致性检验过程,同时提高了评估结果的客观性及模糊综合评判的可信度。最后对两台潮流能发电装置实测数据进行评估分析,验证了该评估方法的有效性。

Currently, no offshore test field has been built for experiment, test and evaluation of tidal current energy generating device in China. The study of tidal current energy generation device performance integrated assessment method is an important part of the theoretical study for construction of an offshore test field, providing a reliable basis for improving the performance of tidal current energy generating device. On the basis of fuzzy comprehensive evaluation model using gray relational theory revision subjective weights, after analyzing performance indicators of tidal current energy generation device, the hierarchical model of device integrated assessment was given. By standardizing the indicators raw data, index values were in the （0,1） , and the complexity of the calculations was reduced. Using the coefficient of variation and correlation corrected initial weight, a comprehensive weight value and the final assessment results of tidal current energy devices and more indicators were calculated. This method not only simplifies the process of standard AHP consistency test, but also avoids excessive subjective assessment results, improving the fuzzy comprehensive evaluation of credibility. The measured data of two units of tidal current energy generation devices were evaluated, and the effectiveness of the assessment methods was verified.
