标题： Decomposition Problem in Process of Selective Identification and Localization of Voltage Fluctuations Sources in Power Grids

摘要： 电压波动是电力系统中常见的干扰，因此，有效且选择性地识别和定位单个电压波动源对于减小此类干扰至关重要。在识别和定位扰动负荷的过程中，通过使用级联的模块：解调、分解和传播评估，可以实现选择性。 这种方法的有效性与所使用的分解方法密切相关。本文介绍了用于选择性识别和定位电压波动源的分解过程问题，其中增强了经验小波变换（EEWT）算法作为分解方法。 文章展示了来自实际电力系统的选定研究结果，在这些结果中，所选方法导致了电压波动源识别和定位过程中的错误。基于获得的研究结果，讨论了与分解过程相关的此类错误的潜在原因。 显示英文摘要

摘要： Voltage fluctuations are common disturbances in power grids, therefore the effective and selective process of identification and localization of individual voltage fluctuations sources is necessary for the minimization of such disturbances. Selectivity in the process of identification and localization disturbing loads is possible by the use cascade of blocks: demodulation, decomposition and propagation assessment. The effectiveness of this approach is closely related to the used method of decomposition. The paper presents the problem of decomposition process for the selected method of selective identification and localization of voltage fluctuation sources, in which the algorithm of enhanced empirical wavelet transform (EEWT) is used as the decomposition method. The paper presents selected research results from the real power grid, for which the result of selected approach causes mistakes in the process of identification and localization of voltage fluctuations sources. The potential causes of such mistakes related to the decomposition process are discussed on the basis of obtained research results.
