Challenges in the Proper Metrological Verification of Smart Energy Meters
Antonio Bracale, Jakub Janowicz, Piotr KuwaÅek +1
The most common instruments currently used to measure active/reactive energy and power quality indicators are smart energy meters (EM). Unfortunately, the verification of such mete…
Assessment of Errors of Fundamental Frequency Estimation Methods in the Presence of Voltage Fluctuations and Distortions
Antonio Bracale, Pasquale De Falco, Piotr KuwaÅek +1
The fundamental frequency is one of the parameters that define power quality. Correctly determining this parameter under the conditions that prevail in modern power grids is crucia…
Decomposition Problem in Process of Selective Identification and Localization of Voltage Fluctuations Sources in Power Grids
Piotr KuwaÅek
Voltage fluctuations are common disturbances in power grids, therefore the effective and selective process of identification and localization of individual voltage fluctuations sou…
Laboratory Setup for Testing Low-Frequency Disturbances of Power Quality
Piotr KuwaÅek, Grzegorz WiczyÅski
Low-frequency disturbances of power quality are one of the most common disturbances in the power grid. These disturbances are most often the result of the impact of power electroni…
Assessment of Diagnostic Capabilities of Methods of Recreation of Voltage Fluctuations
Piotr KuwaÅek
Voltage fluctuations are one of the most common low-frequency disturbances of power quality. Diagnostics of these disturbances are a complex process because voltage fluctuations af…
Multi-Point Method using Effective Demodulation and Decomposition Techniques allowing Identification of Disturbing Loads in Power Grids
Piotr KuwaÅek, Grzegorz WiczyÅski
The paper presents an innovative approach to identifying voltage fluctuation sources in power networks, also considering the localization understood as the indication of supply poi…
