Abstract

The brushless doubly-fed induction generator (BDFIG) presents significant potential for application in wind power systems, primarily due to the elimination of slip rings and brushes. The application of virtual synchronous control (VSynC) has been demonstrated to effectively augment the inertia of BDFIG systems. However, the dynamic characteristics and stability of BDFIG under weak grid conditions remain largely unexplored. The critical stabilizing factors for BDFIG-based wind turbines (WTs) are methodically investigated, and an enhanced VSynC method based on linear active disturbance rejection control (LADRC) is proposed. The stability analysis reveals that the proposed method can virtually enhance the stability of the grid-connected system under weak grid conditions. The accuracy of the theoretical analysis and the effectiveness of the proposed method are affirmed through extensive simulations and detailed experiments.

基于无刷双馈感应发电机的风力涡轮机稳定性分析和增强型虚拟同步控制

无刷双馈感应发电机（BDFIG）在风力发电系统中的应用潜力巨大，这主要是由于它省去了滑环和电刷。虚拟同步控制（VSynC）的应用已被证明能有效增强 BDFIG 系统的惯性。然而，BDFIG 在弱电网条件下的动态特性和稳定性在很大程度上仍有待探索。本文对基于 BDFIG 的风力涡轮机（WTs）的关键稳定因素进行了研究，并提出了一种基于线性主动干扰抑制控制（LADRC）的增强型 VSynC 方法。稳定性分析表明，在弱电网条件下，所提出的方法实际上可以增强并网系统的稳定性。通过大量仿真和详细实验，证实了理论分析的准确性和所提方法的有效性。
