摘 要: | 在各种风力发电系统方案中,双馈感应电机(DFIG)变速恒频风力发电系统以其独特的优点逐渐成为当今风力发电的主流。在分析双馈电机的数学模型及原理的基础上,建立了基于定子磁链定向矢量控制的双馈感应电机风力发电系统模型。运用目前国外广泛应用的电力系统计算机辅助设计软件PSCAD/EMTDC对该系统进行仿真研究,并分析风力发电机运行时的动态性能。仿真结果表明,该控制方式实现了定子端口有功功率和无功功率的解耦控制,具有良好的控制效果。

Abstract: | Among several of wind power generation system schemes, variable speed constant frequency (VSCF) wind power system with doubly fed induction generator (DFIG) are gradually becoming the mainstream in wind power generation at present. The DFIG wind power system model is established based on stator flux oriented vector control method by analyzing the mathematics model of DFIG, the system is simulated using the professional electrical power system analyze software PSCAD/EMTDC, which is being widely applied overseas, and dynamic performance of running for wind power generation. The result indicates the proposed control scheme achieves decoupled control between active power and reactive power at stator port, and it has good control effect. |
