摘要：
Data from wind farm monitoring show that torsional vibration poses severe effect on service life of wind turbines (WTs).Torsional vibration mode of onefold wind farms containing the same WTs is remarkably different from that of single wind turbine. Hybrid wind farms containing different types of WTsare often builtto realize WTs'complementary operation, making torsional vibration more complex. Small signal models for fixed speed induction generator (FSIG), doublyfed induction generator (DFIG) and permanent magnet synchronous generators (PMSG) and three correspondingonefold wind farms were established. Also three kinds of hybrid wind farm models were proposed forDFIG-PMSG, FSIG-DFIG and FSIG-PMSG wind farms. Modal analysis and correlation factors were employed to investigate torsional vibration transfer effect among WTs. Finally, torsional vibration characteristics ofonefold and hybrid wind farms wereconcluded. © 2016, Power System Technology Press. All right reserved.
