| Abstract:In view of the development trend of the safe and reliable operational requirements for the offshore wind turbine generation system, and based on the control principle of the doubly fed wind turbine system, this paper first established the control models of doubly fed induction generator(DFIG) and converter. Second, based on the analysis of the requirements of the power system for the low voltage ride through (LVRT) of a connected-gird wind turbine, different control strategies were analyzed and compared for the LVRT of doubly fed wind turbine system. Finally, given main parameters of a 5 MW offshore doubly fed wind generation system, simulation and comparison were conducted on the protective scheme on the rotor side circuit for two typical low voltage rides-through. The results indicate that the scheme of diode plus IGBT and the chopper of protective resistance have better transient control performances. |
