本文根据现有的风速测量数据和风力涡轮机制造商的数据，分析了英国城市地区的可再生风能资源。选定的风力涡轮机的功率曲线和所考虑的英国城市站点的测量/拟合风速分布用于估计风力涡轮机的最大年能量输出。这些结果进行比较时，通常假设英国平均风速值和平均风速的瑞利分布，而不是测量得到的能量输出。文章认为，英国平均风速和瑞利分布的标准假设不能用于英国城市风资源的正确评估，而威布尔分布则可以通过实测风速数据确定相应的系数k和λ。
Renewable wind resources in UK urban areas are analysed in this paper based on the available wind speed measurements and wind turbine manufacturers' data. Power curves of selected wind turbines and measured/fitted wind speed distributions for considered UK urban sites are used for the estimation of wind turbines maximum annual energy outputs. These results are then compared with the energy outputs obtained when commonly assumed UK mean wind speed values and Rayleigh distribution of average wind speeds are used instead of the measurements. The paper concludes that standard assumptions for UK mean wind speeds and Rayleigh distribution cannot be used for the correct assessment of UK urban wind resources, while Weibull distribution can be used if corresponding factors k and λ are determined from the measured wind speed data.
