风电场变压器选取直接影响风电场投资建设与运行的经济性及安全稳定性。针对该问题，以考虑风功率分布规律的思想，指导风电场变压器选型。首先研究风功率分布规律与变压器运行经济性，包括风功率分布的时间与空间特性、单台与双台变压器在不同工况下的运行特性及相互间的对比分析；继而在此基础上，给出风电场初始规划及后期扩建规划中的变压器选型方案，从而使变压器选取达到规划以及运行中的经济最优，在实现其最优化运行的同时亦可提高其运行可靠性。文中依据现场规划中遇到的实际问题构建了具体算例，通过算例说明与结果分析进一步验证了所提方法的可行性与有效性。

ABSTRACT:Selection of transformers for a wind farm has a lot to do with the investment & construction and the operation economy and stability of the wind farm. Aiming at the above problem,this paper takes the distribution of wind power into consideration to guide the selection of transformers. First,the dis-tribution of wind power and operation economy of transformers are studied,including the spatiotemporal characteristic of wind power,and operation characteristic of one transformer or two transformers in different conditions the paper studies. On this basis,the transformer selection scheme of the prophase and ex-tension stage is obtained,by which the selection of transformers is made economically optimal in the planning and operation phases, and the optimal operation and improvement of the operation reliability can be realized simultaneously. This paper constructs a concrete calculation example based on practical problems in the actual planning,and the result of the example shows that the method proposed is feasible and effective.
