摘要

为探究海上风电场多尾流叠加影响状态下各机位处的湍流强度变化及实际湍流与设计湍流的差异,该文基于实际运行的海上风电场数据采集与监视控制（SCADA）记录数据及IEC标准中所用的尾流附加湍流模型,针对风速、机距对串列机组湍流影响,实测与理论湍流结果差异等方面,经多维对比与分析后得到以下规律：额定风速以下,串列机组的湍流强度增量随风速的增大表现出逐渐升高的趋势,达到额定转速附近时湍流强度接近最大值,然后随风速的提升而降低,这与变速变桨风电机组运行策略有关;随机组间距离的增加,下游机组的湍流强度增量明显降低;基于IEC标准中所用的附加湍流及总体湍流计算方式进行机组设计能够较好地保证风电场中机组运行的湍流安全性。

Abstract

In order to explore the turbulence intensity variation of each turbine position under the influence of multiple-wake interactions in an offshore wind farm, as well as to examine the differences between actual turbulence intensity and designed turbulence, based on the actual SCADA data from an offshore wind farm and the wake-additional turbulence model used in the IEC standard. A multidimensional comparison and analysis was conducted in this paper, which focues on the impact of wind speed and turbine spacing on the turbulence of serial turbines, and the discrepancies between the measured turbulence intensity and the theoretical predictions. The following laws were obtained: under the rated wind speed, the increment of turbulence intensity for serial turbines shows a trend of gradually increasing with the wind speed, reaching near-maximum turbulence intensity when approaching the rated rotational speed, and then decreasing with the further increase of wind speed, which is related to the turbine operational strategy of variable rotate speed and variable pitch angle. With the spacing of the downstream turbine increased, the turbulence intensity is reduced. When designing wind turbines based on the methods for calculating additional and overall turbulence as specified in the IEC standards, it can effectively ensure that the wind turbines within a wind farm operate within a safe turbulence environment.
