论文摘要
本文介绍了一项学术界联合案例研究，该案例是为了量化和比较散布在中型风电场的多个涡轮机的功率生产性能的多年变化。该分析称为时空性能比较。电力性能分析的一个关键方面是控制风和环境投入。这项研究以顺序的方式采用了两个主要建模组件来对多个输入条件进行严格控制 - 一种协变量匹配方法，然后进行基于高斯过程模型的功能比较。该分析方法应用于在中等复杂地形上容纳66台涡轮机的风电场。电力生产和环境数据范围近四年，在此期间，涡轮机经过了多次技术升级。时空分析列出了定量和全局图，显示了涡轮机相对于彼此的差异以及它们中的每个人的变化如何随时间变化。
This paper presents an academia-industry joint case study, which was conducted to quantify and compare multi-year changes in power production performance of multiple turbines scattered over a mid-size wind farm. This analysis is referred to as a space-time performance comparison. One key aspect in power performance analysis is to have the wind and environmental inputs controlled for. This research employs, in a sequential fashion, two principal modeling components to exercise tight control of multiple input conditions -- a covariate matching method, followed by a Gaussian process model-based functional comparison. The analysis method is applied to a wind farm that houses 66 turbines on a moderately complex terrain. The power production and environmental data span nearly four years, during which period the turbines have gone through multiple technical upgrades. The space-time analysis presents a quantitative and global picture showing how turbines differ relative to each other as well as how each of them changes over time.
