Abstract

This article presents a set of methods for the extraction of features from transient events in power systems, using EMT (Electromagnetic Transients) simulations. The main approach is based on the application of the wavelet transform to transient signals, allowing for the analysis and characterization of various types of transient events. Based on the information obtained from the wavelet transform, specific methods such as impedance analysis, energy, peaks, and selectivity indices are developed and applied. These methods provide useful tools for the identification and classification of transient events, constituting a basis for the characterization of various types of disturbances in power systems. The techniques developed enabled the extraction of unique and distinguishing features of photovoltaic resources, which can later be applied to non-intrusive monitoring of these systems.

电力系统中分布式能源集成产生的电磁瞬变分析的创新方法

本文提出了一套利用EMT（电磁瞬变）仿真从电力系统暂态事件中提取特征的方法。主要方法是基于小波变换对瞬态信号的应用，允许对各种类型的瞬态事件进行分析和表征。基于小波变换得到的信息，开发并应用了阻抗分析、能量、峰值和选择性指标等具体方法。这些方法为暂态事件的识别和分类提供了有用的工具，为表征电力系统中各种类型的干扰奠定了基础。所开发的技术能够提取光伏资源的独特和显著特征，这些特征可以稍后应用于这些系统的非侵入性监测。
