抽水量

For wind machines and pump load widely used in industry , the more desirable speed adjustment strategy is doubly fed regulation in order to save energy
对于工业中大量应用的风机、泵类负载，为实现节能，比较好的调速方案是采用双馈调速。
The doubly fed induction machines speed adjustment system has the advantage of good speed adjusting behavior , low harmonic pollution , high reliability and cheap productive price . due to these characteristics , it is especially suitable for those situations with high voltage level , high power and not large speed adjustment range , such as wind machines and pump load
感应电机的双馈调速系统具有调速性能好、低谐波污染、可靠性高及造价低廉等优点，特别适合于高电压、大功率且调速范围不大的场合，尤其适用于风机、泵类负载。
