| 摘 要： | 随着风力发电的电网穿透率的增加,风电系统与电网之间的相互影响也越来越大。风电系统输出功率的波动性和间歇性对电网的电能质量及其稳定性将产生较大的影响;与此同时,电网故障也会给风电系统带来一系列的暂态过程,甚至会危及到风电系统的安全运行。本文针对基于储能的并网永磁直驱风力发电系统的运行特点,提出了一种可行的综合控制策略,在使风电系统输出较为平滑的功率的同时,还具有较强的低电压穿越能力,使风电系统基本不受电网故障的影响。仿真结果很好地证明了所提出的控制策略的正确性和有效性。

| Abstract: | The increasing wind power penetration poses significant technical problems for the electric power systems.The intermittent and fluctuant output power of wind generators has a great impact on the power quality and power system stability.On the other hand,the grid-side faults influence the transient processes of wind generators.In this paper,an integrated control strategy is proposed based on the characteristics of directly driven wind turbine with permanent magnet synchronous generator(D-PMSG).The D-PMSG is incorporated with energy storage system,which smoothes the output power and enhances the low voltage ride-through(LVRT) capability of the wind generator.The effectiveness of the control strategy is verified in the numerical simulations. |
