| 摘 要： | 鉴于目前虚拟同步电机(VSG)的研究主要集中在控制系统的改进上,缺乏对实际虚拟同步发电机控制参数的量化认识.对此,建立了虚拟同步电机线性化时域函数模型,考虑虚拟同步机惯量和阻尼参数之间的耦合性,提出了一种基于岭估计法的虚拟同步机等效惯性和阻尼系数辨识方法.在输出功率阶跃变化时,利用岭估计法对VSG惯量和阻尼参数进行辨识...

| Abstract: | Currently,the study of virtual synchronous generators(VSG)mainly focuses on the improvement of the control system,and lacks a quantitative cognition of the control parameters of actual VGS.In view of the above problems,the linear time-domain function model of VGS is built.Considering the correlation between the inertia and damping parameters of VGS,an identification method of the equivalent inertia and damping of VGS based on ridge estimation is proposed.The inertia and damping parameters of VSG can be identified by ridge estimation when the step changes of output power emerge.The errors of the ridge estimation method is compared with the traditional least squares method through simulation and RT-LAB hardware-in-the-loop experiments.Simulation and experimental results show that the proposed method has better identification accuracy. |
