摘要: This paper proposes a switching angle controller (SAC) and an automatic generation (AGC) for the doubly-fed induction generator (DFIG) to control frequency of DFIG-based wind power penetrated systems. The concept virtual rotor DFIG is defined. controlled by SAC in bang-bang manner such that active regulated provide support external grids. output also used pitch offer short-term regulation mechanical input DFIG, long-term achieved with AGC. Small-signal analysis undertaken verify effectiveness Simulation studies are carried out two-machine system modified Kundur four-machine two-area system, respectively. performance DFIGs having different configurations investigated. Modal evaluate effect AGC providing additional damping oscillation modes system.
