Tóm tắt

This paper presents the dynamic stability enhancement results of four parallel-operated permanent-magnet generator (PMG)-based offshore wind turbine generators (WTGs) connected to an onshore power grid using a static VAR compensator (SVG). The operating characteristics of each WTG are simulated by an equivalent aggregated 5-MW wind PMG while the onshore power system is simulated by a synchronous generator (SG)-based single machine infinite bus (SMIB) system. A damping controller of the proposed SVG is designed to render adequate damping to the dominant modes of the studied SG. A frequency-domain as well as a time-domain performances are carried out. It can be concluded from the simulation results that the proposed SVG joined with the designed damping controller can effectively improve the stability of the studied system under serious disturbance conditions.
