    摘要:

    提出了一种改进稀疏表征的两步法实现欠定模型下动态谐波阻抗矩阵的估计。首先测量关注母线节点的谐波电压值,基于稀疏域二维最小偏差角判断谐波阻抗矩阵的变化时刻,进而估计动态变化的谐波阻抗矩阵并获得实时的谐波源数目。通过MATLAB仿真软件进行IEEE-14节点系统的仿真验证,验证改进稀疏表征的两步算法估计谐波阻抗的精确性和合理性。

    Abstract:

    A two-step method to improve the sparse representation is proposed to estimate the dynamic harmonic impedance matrix under the underdetermined model.First measured on bus node harmonic voltage value,based on the two-dimensional sparse domain minimum deviation Angle of the change of the harmonic impedance matrix moment,and then estimates the dynamic change of the harmonic impedance matrix and obtain the real-time harmonic source number.Simulation verification of IEEE-14 node system was carried out through MATLAB simulation software to verify the accuracy and rationality of two-step algorithm for estimating harmonic impedance improved sparse representation.
