Abstract

Two problems of structural analysis of electrical quantities are considered: the suppression of spectral components and selection of orthogonal harmonic components of unknown frequency. Each procedure starts with a minimum possible number of counts of the electrical variable to be processed and, as a consequence, with a minimum number of operations. The tools of structural analysis include a multilink adaptive filter, each link of which tuned to suppress one component of the observed electrical value. Structural analysis is completed with a separate procedure of selection of orthogonal components of the fundamental frequency component, the value of which is to be determined. The tuning of the real-time multilink filter done in the form of an iteration process. At each iteration step, only one link of the filter is to be tuned.

评估具有少量计数的电量基本元素的参数

摘要

考虑了电量结构分析的两个问题：频谱​​分量的抑制和未知频率的正交谐波分量的选择。每个过程都以要处理的电气变量的最小可能数量开始，因此要以最小数量的操作开始。结构分析的工具包括一个多链路自适应滤波器，其每个链路都经过调整以抑制观测到的电值的一个分量。结构分析是通过选择基本频率分量的正交分量的单独过程来完成的，其值待确定。实时多链路滤波器的调整以迭代过程的形式完成。在每个迭代步骤中，仅调谐滤波器的一个链接。
