Abstract:

随着风电的快速发展,其规模化接入会对系统的低频振荡带来较大的影响,采用希尔伯特-黄变换法(Hilbert-Huangtransform,HHT)分析风电功率波动及其对电力系统低频振荡的影响。将风电功率进行经验模态分解(empiricalmodedecomposition,EMD),采用HHT变换和曲线拟合,进而得到不同振荡模态的阻尼比,以此作为低频振荡的判断依据。以WSCC3机9节点系统模型为例,对比分析同幅值不同频率和同频率不同幅值的标准正弦风电功率波动对系统低频振荡的影响。针对实际风电功率,根据波动率和能量密度可知功率的波动集中于中频段(0.01’1Hz),因而对系统低频振荡的影响更为严重,对风电功率波动的平抑成为必要。
