Abstract  

Against the backdrop of Typhoon Maria (2018), the mesoscale weather research and forecasting model (WRF) coupled with a wind-farm parameterization scheme was used to investigate the wake and power characteristics of wind farms in the complex mountainous terrain of the southeastern coast under typhoon influence. Results showed that during the phase influenced by the typhoon’s peripheral circulation (under low wind speed conditions), the topographic effects significantly modulated the incoming flow to the wind farm. When the incoming flow was northerly, the topographic shielding reduced the power output of units 1 to 4 by approximately 35% compared with units 21 to 24. The atmospheric motion in the wake area of the wind farm was primarily characterized by horizontal transport. The irregular layout of the wind farm, constrained by the complex mountainous terrain, resulted in a high sensitivity of unit power output to changes in incoming flow direction, with significant power output differences observed among adjacent units even with minor directional changes. During the typhoon impact period, the overall incoming wind speed increased, leading to full power generation at the wind farm, and the influence of wake interference among units on power output was minimal.

Key words： typhoon      wind farm      wake      power output      mesoscale model

台风影响下东南沿海山地风电场尾流与功率特征研究

以2018年第8号台风“玛莉亚”为背景，基于中尺度天气预报模式（WRF）耦合风电场参数化模型，研究东南沿海复杂山地地形风电场在台风影响下的尾流与功率特征. 结果表明，在台风外围环流影响阶段（低风速条件下），地形效应对风电场来流产生显著调制作用. 当来流风向偏北时，1到4号机组受地形遮蔽效应影响，功率输出较21到24号机组降低约35%，风电场尾迹区的大气运动主要表现为水平输送特征. 受复杂山地地形制约的风电场不规则布局，导致机组功率输出对来流风向变化极为敏感，相邻机组在风向微小变化下呈现显著的功率输出差异. 在台风影响期间，整场来流风速增大，风电场满发，机组间尾流干涉对功率输出的影响较小.
