摘要 提出了一种新的基于超导磁储能系统的变速恒频风力发电机励磁系统,通过斩波器把超导磁体引入到双馈感应发电机(DFIG)的励磁系统中。利用超导磁体的高效储能和快速响应特性,在DFIG变速恒频运行过程中,超导磁体可以根据不同的控制目标对系统进行功率补偿,有效地提高DFIG并网风力发电系统的运行性能,提高系统运行的稳定性。在MatlabSimulink环境下,通过仿真分析验证了该系统的基本运行特性,仿真结果说明该系统有良好的动态响应特性。 This paper proposes an excitation .system of variable speed constant frequency (VSCF) wind power generator based on Superconducting Magnet Energy Storage (SMES), with the application of the superconducting magnet in the excitation system of Doubly-Fed Induction Generator(DFIG) through the chopper. Due to the high efficient energy storage and quick response features of superconducting coil, the system can realize the double function of variable speed constant frequency operation of the wind power system and the power compensation for the grid. According to the control objective of the system, the system can provide power compensation for the grid connected, which can improve the operation performance of the DFIG and contribute to the stability. Using MATLAB simulation, the functions of this system are verified and good dynamic characteristics are shown.
