摘　　要：为改善独立微网中由于系统惯量小导致的频率暂态稳定性差的问题,该文研究利用风电机组虚拟惯量参与调频的控制算法。首先,分析风电机组虚拟惯量控制(VIC)机理和其存在转速快速恢复和超调过程造成调频能力下降的问题,并说明传统比例微分(PD)控制的原理;然后,利用系统频率动态响应方程,推导虚拟惯量一阶自抗扰控制(ADRC)的设计过程;最后,通过仿真和实验验证得出ADRC比PD控制优势在于能降低转速恢复速度和抑制转速超调,能更充分的释放虚拟惯量,因此ADRC进一步减小了微网暂态频率偏差和稳定时间。In order to improve the frequency transient stability in an independent micro-grid,this paper studies the algorithm of using the wind turbine virtual inertia to participate in frequency regulation.Firstly,the mechanism of wind turbine virtual inertia frequency regulation is analyzed,and the principle of tradition PD virtual inertia control is described.Secondly,using the system frequency dynamic response equation,the designing process of one-order ADRC virtual inertia control is deduced.Thirdly,through simulation and experiment verification,it is concluded that ADRC is superior to PD in that it can reduce the recovery speed of the rotating speed and suppress the rotating speed overshoot,and more fully release the virtual inertia,so ADRC algorithm can further improve the transient frequency deviation and the settling time.
