Taken the cut-in and cut-off windspeed of wind turbine into account, a concept named active wind power density was presented.
通过对风功率密度进行分析，考虑到风机工作风速区间，提出有功风功率密度概念。

The paper introduces the structure and characteristic of soft cut-inwind turbine control system using a dual speed asynchronous generator.
本文介绍了双速电机软并网型风力发电机组控制系统的构成和特点。
