摘要:
针对风能功率波动影响直驱风力发电系统输出电能质量问题,研究基于一阶滤波器的混合储能功率平滑控制方法:采用一阶滤波器将风能波动功率分离为低频和高频分量,分别由蓄电池补偿其中的低频分量,由超级电容补偿其中的高频分量,从而实现风电系统输出功率平滑、运行可靠。讨论了一阶高通滤波器转折频率的选取对功率平滑控制效果的影响,提出了合理的一阶滤波器转折频率选取办法,并进一步给出了基于一阶滤波器法的超级电容容量选取方法。此外,为避免因过压或欠压而造成超级电容损坏而采用电压预先控制方法进一步改善了基于一阶滤波器法的功率平滑控制性能;仿真及实验结果验证了所提出功率平滑控制方法的有效性
Abstract:
Aiming at mitigating wind fluctuation effects on the output power quality, the power smoothing control was discussed in detail which was based on the first-order filter (FOF) in the hybrid energy storage integrated in the direct-drive wind power generation system. The FOF is exploited to separate the high/low frequency fluctuating components from direct drive wind power, then the low frequency power component is buffered by battery energy system and the high frequency power component is softened by super capacitor energy system. In the paper, the influence of the first-order high pass filter parameters on the wind power smoothing control was analyzed, and a reasonable first-order filter turnover frequency was determined as well as super capacitor nominal capacity. In addition, the power pre-control was adopted to improve the performance of the power smoothing control method, which was based on first-order filter, in order to protect super capacitor from over-voltage or under-voltage effect. The effectiveness of the proposed power smoothing control method was verified by the simulation and experiment results.
