摘要
Developing effective electromagnetic transient models of wind turbine generators is essential for the studies of grid-integrated wind generation. However, the manufacturers keep their key strategies a secret, which hinders the modeling of wind turbine generators. To address this issue, massive fault ride-through field tests were conducted on direct-driven wind turbine generators, and generic fault ride-through response waveforms for symmetrical and asymmetrical voltage dips were proposed. The expressions of active and reactive power responses were derived to formulate the different fault ride-through stages, including the fault ride-through control process during a fault, post-fault recovery control process, and their switching transients. Further, a generic active and reactive current reference generator was designed, and thus a generic electromagnetic transient modeling method for complete fault ride-through processes of direct-driven wind turbine generators was proposed. Finally, the proposed modeling method was validated by field tests of practical direct-driven wind turbine generators. © 2022 Chin. Soc. for Elec. Eng.
