Abstract

The wind farm is a collection of all wind turbine generators situated at a particular distance. The wind speed and wind direction play an important role in wind farm power calculation. The power curve of the wind farm is not simply the summation of the wind turbine’s power curve. It is complex due to the intermittent nature of wind speed and its direction. The power curve is obtained from the data taking the wind speed and wind power at that speed. There are many logistic functions used in the literature to analyze the wind power curve that helps to calculate wind farm power output and energy generated. In this paper, the 3-parameter deterministic process (3P-DP) method is used for wind power curve calculation. The wake effect is analyzed by Jensen’s model with wind speed and wind direction. The wind farm power is obtained from the new proposed formula and compared with the already existing one. The results are verified from real data obtained from the literature.

考虑风力机尾迹效应的风向对风电场输出功率计算的影响

风电场是位于特定距离的所有风力涡轮发电机的集合。风速和风向在风电场功率计算中起着重要的作用。风电场的功率曲线不是简单的风力发电机功率曲线的总和。由于风速及其方向的间歇性，它是复杂的。功率曲线由风速和该风速下的风力数据得到。文献中有许多逻辑函数用于分析风电曲线，有助于计算风电场输出功率和发电量。本文采用三参数确定性过程(3P-DP)法进行风电曲线计算。采用考虑风速和风向的Jensen模型对尾流效应进行了分析。根据新公式计算风电场功率，并与已有公式进行比较。用文献中的实际数据对结果进行了验证。

期刊介绍： Having been in continuous publication since 1977, Wind Engineering is the oldest and most authoritative English language journal devoted entirely to the technology of wind energy. Under the direction of a distinguished editor and editorial board, Wind Engineering appears bimonthly with fully refereed contributions from active figures in the field, book notices, and summaries of the more interesting papers from other sources. Papers are published in Wind Engineering on: the aerodynamics of rotors and blades; machine subsystems and components; design; test programmes; power generation and transmission; measuring and recording techniques; installations and applications; and economic, environmental and legal aspects.
