This paper presents a practical validation procedure of the estimated primary samples obtained by DSE-based instrumentation channel error correction. With our previously published research of DSE -based instrumentation channel error correction, the accurate estimation of primary samples can be obtained. The conventional way to validate the estimated primary samples relies on comparing the estimated primary samples with the actual ones. However, this conventional validation method won't work in industry practice since the actual primary samples cannot been known in industry field. The proposed validation procedure aims to validate the estimated primary samples without the knowledge of actual primary samples. The proposed validation method is based on the comparison of substation-wide dynamic state estimation (SDSE) results obtained using the legacy primary samples and the estimated primary samples, respectively. The proposed method derives three validation indicators to validate the estimated primary samples. The validation results have been demonstrated by numerical experiments.

本文介绍了通过基于 DSE 的仪器通道纠错获得的估计原始样本的实际验证程序。通过我们之前发表的基于 DSE 的仪器通道纠错研究，可以获得原始样本的准确估计。验证估计的原始样本的常规方法依赖于将估计的原始样本与实际样本进行比较。然而，这种传统的验证方法在工业实践中不起作用，因为在工业领域无法知道实际的原始样本。提议的验证程序旨在在不了解实际初级样本的情况下验证估计的初级样本。所提出的验证方法基于对分别使用传统初级样本和估计初级样本获得的变电站范围动态状态估计 (SDSE) 结果的比较。所提出的方法推导出三个验证指标来验证估计的原始样本。数值实验证明了验证结果。
