Question

英语翻译
A lead-lag controller is used,and the loop gain bandwidth
is designed for 1 Hz.A fast speed loop will respond more
quickly to changes in the load,such as gusts of wind.This will
cause the generator torque to respond quickly,thereby causingthe power into the grid to change rapidly,mirroring the wind
gusts.However,a slow speed loop will allow the generator
to accelerate or decelerate as the wind changes,thus using the
rotational energy of themachine as a buffer to smooth the power
into the grid [8].
C.Design of CQs
The reactive power outer loop is designed by relating stator
reactive power Qs to irq.It is,again,helpful to use the magnetizing current
As explained earlier,the magnetizing current imq can be approximated
to be constant.Equation (13),then,follows:
A PI controller is used,and the loop gain bandwidth is designed
for 1 Hz.
D.Design of Unbalance Compensation Controllers Cd,comp
and Cq,comp
The Cd,comp and Cq,comp controllers shown in Figs.2 and 3,
respectively,come into effect only in the presence of a statorvoltage
unbalance.They supplement the output of the nominal
operation controllers Cird and Cirq to remove the 100 Hz disturbance
from the torque and reactive power.It is not enough to
simply increase the gain of Cird and Cirq.Removing the second
harmonic from ird and irq will not completely remove the
second harmonic from the torque and reactive power,although
it can reduce it.

Answer 1

带头-滞后控制器使用,增益频宽为1赫兹.快速环路将更加迅速地回应变化的负荷,如风浪.这会造成发电机的扭矩迅速作出反应,从而causingthe电力进入电网迅速变化,风灾的阵风.不过,速度慢了河套将使发电机加快或减慢风力变化,因此利用转动themachine作为缓冲,顺利进入电力电网[8].三设计cqs功外环设计与静功qs为irq.这是一次有益的利用激磁电流说过 磁化电流过量可近似为常数.方程(13),然后如下:API控制使用,增益频宽为1赫兹.丁设计不平衡补偿控制器cd,comp和cq,comp裁,comp和cq,comp控制器列figs.2号和3号,开赛前只存在一个statorvoltage失衡.他们补充输出的名义运作控制器cird和cirq取消100赫兹的干扰,从 转矩与功.这是不够的简单增加增益cird和cirq.清除二次谐波税务局与IRQ不会彻底清除二次谐波从转矩和功 力量,虽然它可以酌减.
