基于风电机组分群的风电可靠性评价方法研究

为了更好地开展风电机组可靠性评价工作，在分析比较国内外风电机组可靠性评价规程的基础上，提出了对风电场风资源、风电机组群、风电场以及单台风电机组可靠性评价的新办法，在新的评价办法中增加风资源以及风电机组群的可靠性评价指标计算方法。与现有评价规程及评价方法相比，新的评价办法更符合中国目前风电机组发展形势及风电机组可靠性管理特点，同时具有数据处理量小，风电场运行与管理人员工作负担轻的优点。

Wind Power Reliability Evaluation Method Based on Wind Power Unit Grouping

In order to evaluate the reliability of wind turbines more effectively, on the basis of analyzing and comparing the wind turbine reliability evaluation procedures at home and abroad, a new method is proposed to evaluate the reliability of the wind farm resource, the wind turbines group, the wind farm and the single wind turbine, The calculation of the reliability indexes of resource and wind turbines group is added to the new method. Compared with the existing evaluation procedures and methods, the new method fits better with the current situation of wind turbine development in China and the characteristics of reliability management of wind turbine units. At the same time, it has the advantages of a small amount of data processing and less burden of wind farm operation and management.
