从而求得快波回旋阻尼功率。
在系统发生功率振荡时，通过改变转子励磁电压的相角调节双馈变速风电机组输出与振荡相关的阻尼功率，达到使风电场能够改善系统阻尼的目的。
During the power oscillation of a power system, a damping active power is injected into the network from the DFIG machine via regulating the rotor excitation voltage Angle.
于是，这就有可能控制一个质量阻尼器的移动或相对地利用低功率来调整建筑物结构的硬度。
It is thus possible to control the movement of a mass damper or adjust the stiffness of a building's structure using relatively little power.
