Suppression of Transient Response Spikes in Diagnostic and Prognostic Datasets
Many diagnostic and prognostic datasets suffer from the extreme effects of transient response spike since it introduces an abrupt change in the values reported in the dataset. This is especially true for electrical power system data where the switching effect is a major contributor to the transient response spikes. Most transient response spikes are harmful to the analysis of data in that they throw off real-time detection of abnormal conditions, and classification of faults. Since the transient response is embedded within the data, removal of the unwanted signals from the data is not always easy and may result in losing the integrity of the information carried by the data. The proposed algorithm in this paper is a multi-resolution filtering approach that is capable of suppressing transient response spikes with minimal damage to neighboring data. Presented here is the theoretical background with some examples from a realistic testbed.
