摘要：

The dynamical and drive system of a doubly-fed induction generator-based wind energy conversion system (DFIG-based WECS) including wind turbine, two-mass drive train is represented using a compacted transfer function based on small signal analysis. The poles and zeros of transfer function are related to parameters of WECS, as well as operating point. The resulting transfer function can be further resolved into two terms: non-torsional term and torsional term. From the transfer function description, it can be readily seen that the shaft parameters, (i.e., shaft stiffness and damping ratio) only affects the torsional term. Furthermore, a transfer function model, which covers drive system, doubly-fed induction generator, power electronic and control system, is developed. The transfer function model provides an in-depth insight into the systemic behavior of DFIG-based WECS. On the other hand, it offers guidelines for design of system parameters. Test studies validate the assertions and demonstrate the application of the methodology. ©2024 Chin.Soc.for Elec.Eng.
