摘　　要：在分析直驱式永磁同步风电机组的基本构成、数学模型基础上,研究了变流器的控制策略。利用PSCAD/EMTDC仿真平台构建了直驱式永磁同步风电机组的仿真模型,仿真分析了阶跃风速下直驱式风电机组稳态运行特性,并仿真研究了额定风速下直驱式风电机组的暂态特性。研究结果表明并网运行的直驱式风电机组具有良好的运行特性,电网故障时直驱式风电机组能够调节无功功率输出,对电网电压的恢复有积极的作用,能提高电网的稳定性。Based on the analysis of the basic structure of direct-driven PMSG wind turbine and its mathematical model, the control strategy of converter was researched. The simulation model of the direct-driven PMSG wind turbine was built on the PSCAD/EMTDC simulation platform, then simulated and analyzed the steady-state operation characteristics in the step wind speed, and the transient characteristics were researched through simulation in the rated wind speed of direct-driven wind turbine. The simulation results showed that the direct-driven wind turbine connecting with the power grid has good operating characteristics. When the fauh occured in the power system, it could regulate reactive power output, having a positive effect on the recovery of grid voltage. Moreover, it could improve the stability of power grid.
