Abstract

Based on the closed-loop frequency domain model of permanent magnet synchronous generator–based wind power generation system (PMSG-WPGS), the stability domain of the control parameters is constructed through the D-partition method in this paper to acquire the range of machine-side converter (MSC) and grid-side converter (GSC) parameters. First, the basic stability domain of the controller parameters is established according to the control structure and transfer function of the back-to-back converter. Then, based on the frequency domain performance indexes, amplitude margin and phase angle margin, the obtained basic stability domain is adjusted to further gain the control parameter values that meet the frequency domain index. Furthermore, the rationality of the stability domain range is verified by drawing root locus curves of variable controller parameters on the machine side and grid side. Finally, the low-power scale experimental platform of PMSG-WPGS is built in the lab to validate the feasibility of the proposed stability domain construction method.
