针对现有柔性直流线路保护耐受高阻、噪声干扰、区内远端高阻故障拒动等问题,提出一种基于行波能谱矩阵相似度的柔性直流线路单端保护方案。通过分析柔性直流电网限流电感的边界作用,得到区内、区外故障电压行波在时域和频域上的差异,利用S变换,构造能谱矩阵,加大区内、区外故障在能量谱分布上的差异,通过主成分分析法降维,减少样本数据的存储空间。利用归一化互相关系数,获得故障能谱矩阵与故障样本矩阵之间的相似度,构造柔性直流单端保护判据,判别区内、区外故障。考虑了架空线路易遭受雷击的因素,构建雷击干扰识别判据。仿真结果表明,所提保护方案不受故障位置、高阻、噪声干扰等影响。
For the problems of high-resistance tolerance
noise interference
and operation refusal on remote high-resistance internal fault of the existing flexible DC line protection
this paper proposes a single-end protection scheme for the flexible DC transmission line based on the similarity of energy spectrum matrix of traveling waves. By analyzing the boundary effect of current limiting inductors in the flexible DC power grid
the difference of voltage traveling waves of internal and external faults in time and frequency domains is obtained. The S-transform is used to construct the energy spectrum matrix to increase the difference of energy spectrum distribution between internal and external faults. The principal components analysis is used to reduce the dimension and the storage space of sample data. By using the normalized cross-correlation coefficient
the similarity between the fault energy spectrum matrix and the fault sample matrix is calculated
and the single-end flexible DC protection criterion is constructed to distinguish the internal and external faults. Considering the factor that overhead lines are vulnerable to lightning
the lightning interference identification criterion is constructed. Simulation results show that the proposed algorithm is not affected by the fault location
the high resistance and the noise interference.
