大连近海风电场风机机组的选型与布置初探

Explore on the selection of wind turbine generator in offshore wind farm of Dalian

风机的选型与布置是风电场建设可行性研究的重要内容,对风电场的建设造价和投产后的发电效益有重要的影响。文章在大连近海风资源评估的基础上,综合考虑国内外风力发电机组的制造水平、技术成熟程度,选择4种机型,布置在两个参考场址,预测其理论发电量,通过技术经济比较,选出最佳机型。一号场址的水文地质条件比较利于风机布置,可安装34台单机容量为3 MW的风力发电机组,布置方式为2排17列,年上网发电量约为26 262万kWh。

The selection and arrangement of wind turbine generators are important in the feasibility re- search of wind farm construction,which has a important influence on the cost and power benefit.Base on the evaluation of wind resource in Dalian and wind turbines＂ manufacture level at home and abroad, four kinds of turbines were choosed arranged energy,Choose the most suitable wind turbine t site was determined to be the optimal site in two referenced sites to predict the theoretical generated by compareing the technology and economics. Finally No. for wind turbine arrangement, in which 34 wind turbines with the capacity of 3 MW could be installed by 2 rows and 17 columns, the energy of 262.62 million kWh was generated on-grid each year.
