风电场建设中的风力发电机组选型

Type selection of wind turbine units for wind farm

风力发电机组的选型不仅关乎到风电场建设造价,还影响投产后的发电量和运营成本,以及最终的上网电价,因此在风力发电场设计和建设中,风力发电机组的选型就显得很重要。文中结合慈溪风力发电场风力资源、地质情况和当地电网情况,依据风力发电机组等级等基本参数,综合经济性和LEC安全性评价指标,对风电场的风电机组进行选型分析,风电场最终机组选为Ⅱ类风机。

The type selection of wind turbine is related to not only the construction cost of wind farm, but also the operating cost and power output when putting into operation, as well as the final power purchase price, therefore, the type selection of wind turbine is very important in the process of the design and construction of wind farm. With the combination of wind resources, geolog- ical conditions and the local power grid for Cixi Wind Farm, the analysis on the type selection of the wind turbine units for the wind farm are made based on the basic parameters of grade of the turbine unit and integrated with the economic performance and the indexes of the safety assessment made with LEC method, and then the turbine units of Class Ⅱ. are finally selected for the wind farm.
