摘　　要：建立包含多种非线性风速、定桨失速型风轮机、机械传动装置、多极低速电励磁双凸极发电机以及电气控制模型在内的风力发电机组整体动态数学模型;应用MATLAB软件Simulink/SimPowerSystems环境,以数学模型为基础搭建了新型电励磁双凸极风力发电机组的数字仿真工具;以随机风和渐变风为例,利用数字仿真工具对一台2 kW、24/16极电励磁双凸极发电机的工作特性进行了仿真研究。仿真与实验结果表明,建立的数字仿真模型能够较好地反映新型电励磁双凸极风力发电机组的实际工作特性,为大规模非并网风电系统基础研究提供了有力的工具。An integral dynamic model of a wind power generation system containing non-linear wind speeds, a fixed-speed stall-regulated wind turbine, mechanical transmission devices, a multi-pole low-speed doubly salient electro-magnetic generator, and electric control model were established in this paper with Simulink/SimPowerSystems of MATLAB toolbox. The mathematical simulation tool of the novel doubly-salient electro-magnetic machine wind power generation system was constructed on the basis of the mathematical model. Simulation of operational performances of a 2 kW, 24/16 doubly salient electro-magnetic generator （DSEG） was carried out and simulation results are compared with experiment results, which demonstrate that the mathematical simulation model proposed in this paper could reflect the actual performance of the novel doubly salient electro-magnetic machine wind power generation system, providing an effective tool for basic research of large-scale non-grid-connected wind power generation system.
