摘要：针对跨高度范围内大气密度对风机全压、流量和功率的显著影响，利用风机相似性原理得到了任意高度及任意转速条件下风机的全压、流量三维曲面数据和全压、功率三维曲面数据，对跨高度范围内的风机特性进行仿真分析，研究了高度与风机特性之间、相同高度下风机各个特性之间的变化关系。风机特性随运行高度的变化而变化，通过对跨高度风机在不同高度下的特性研究，在考虑大气密度变化的条件下，实现了风机效率的优化控制。

Abstract: There are many problems when the brushless doublyfed induction generator (BDFIG) operates at the status of connecting to power grid using the traditional scalar control mode based on tracking generation voltage. A gridconnecting control strategy based on the grid voltage space vector and a reactor connected between the brushless doubly fed generation system and the power grid,was proposed in this paper. So, the voltage vector of power generation system, the grid voltage vector and the voltage vector of reactor constitute a vector triangle to realize the gridconnected control for BDFIG. Experimental results verified the effectiveness of the proposed control method in this paper.
