摘　　要：近年来,风电行业在全球都获得了快速发展。但传统风电机组在城市环境中却难以正常工作。为了实现在城市中进行微风发电,就需要探究其原因,对城市风场特性进行分析和研究。本研究以南京作为代表城市,使用便携式风速仪和固定式气象站对城市环境中的风场特性进行了观测和分析。根据结果,总结出影响风力发电效果的城市风场特性主要有三大方面:低风速、频变风向和湍流。最后对照传统风力发电选址的技术标准提出城市风力发电的发展方向。In recent years, the wind power industry in the world has achieved rapid growth. But traditional wind turbine is difcult to work properly in an urban environment. A preliminary study of urban wind farm characteristics was made in order to fnd out the reason and make the generation breeze in urban area to become reality. In this study, portable anemometer and fxed weather station were used to observe and analysis for the characteristics of urban wind farm in Nanjing city, which was made as representative. According to the measurement results, the three mainly infuencing factors of urban wind farm characteristics that impact the efect of wind power generation are:low wind velocity, frequent changing wind direction and turbulence. At last, the direction of development for urban wind power generation was put forward according to the technical standards of address selection for traditional wind power generation.
