本文介绍了一个电力行业联合案例研究，进行量化和比较分散在一个中型风电场的多个涡轮机的发电性能的多年变化。该分析被称为空时性能比较。功率性能分析的一个关键方面是控制风力和环境输入。本研究采用，在一个连续的方式，两个主要的建模组件，以严格控制多个输入条件协变量匹配方法，其次是高斯过程模型为基础的功能比较。该分析方法适用于一个风力发电场，房子66涡轮机在一个中等复杂的地形。发电和环境数据跨越近四年，在此期间，涡轮机经历了多次技术升级。时空分析提供了一个定量和全局的图像，显示了涡轮机之间的相对差异以及每个涡轮机如何随时间变化。? 2021爱思唯尔有限公司保留所有权利。
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 midsize 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 conditionsda 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. ? 2021 Elsevier Ltd.
