摘要
本文利用已投产风电场的主导风向开展尾流损失分析,对风电场内风力发电机组分成4组,统计风电场之间尾流损失电量,结果表明,受到外部风场对于该风电场的尾流影响,西方向损失约190h,东南方向损失约268h,整体损失近458h,占总发电量21%。可见,在未来项目规划布局时,应将周围风电场的影响纳入风险影响因素。
In this paper, the wake loss analysis is carried out by using the prevailing wind direction of the wind farm that has been put into operation. The wind turbine components in the wind farm are divided into four groups, and the wake loss are calculated between the wind farms. The results show that by the the external wind farm effect, the west lost about 190 hours and the southeast lost about 268 hours, the whole loss was nearly 458 hours, accounting for 21% of the total power generation. It can be seen that in the future layout planning of the project, the impact of the surrounding wind farm should be included in the risk factor.
