Abstract

Based on advanced mechanical speed regulating and servo control techniques, a hybrid-drive wind turbine (WT) set with a generator front-end nonpolar speed regulator was proposed to realize its working mode of variable-speed constant-frequency (VSCF).The dynamic model for the WT’s transmission system was established using the lumped mass method and Lagrange’s equations.Based on the derived dynamic equations, The Simulink simulation model for a 1.5 MV WT set with front-end speed-regulating was built to deeply study its operation characteristics including speed-regulating accuracy, power consumption, current harmonic wave pollution and low-voltage ride-through (LVRT) capability.The results showed that under condition of different wind speeds, the proposed WT set can not only output constant-frequency electric power with smaller power dissipation (less than 15.25% of output power) of speed regulating, but also effectively suppress current harmonic wave pollution and improve the WT set’s LVRT capability; the practicability and superiority of the proposed WT set are verified with theoretical analysis and simulation study.
