An Alternate Representation of the Vector of Apparent Power and Unbalanced Power in Three-Phase Electrical Systems

Blasco Espinosa, Pedro Angel; Montoya-Mira, Rafael; Diez-Aznar, José-Manuel; Montoya Villena, Rafael (MDPI AG, 2020-06)

[EN] Low-voltage distribution systems are typically unbalanced. These ine¿ciencies cause unbalanced powers that can significantly increase the apparent power of the system. Analysing and measuring these ine¿cient powers ...
Compensation of Reactive Power and Unbalanced Power in Three-Phase Three-Wire Systems Connected to an Infinite Power Network

Blasco Espinosa, Pedro Angel; Montoya-Mira, Rafael; Diez-Aznar, José-Manuel; Montoya Villena, Rafael; Reig-Pérez, Miguel Jorge (MDPI AG, 2019-12-21)

[EN] The compensation of an electrical system from passive compensators mainly focuses on linear systems where the consumption of charges does not vary significantly over time. In three-phase three-wire systems, when the ...
Formulations for the apparent and unbalanced power vectors in three-phase sinusoidal systems

León-Martínez, Vicente; Montañana-Romeu, Joaquín (Elsevier, 2018)

[EN] Buchholz's apparent power and its derived unbalanced power, determined from the quadratic difference between the apparent power and the positive-sequence apparent power, are formulated in this paper in vector notation ...
Instantaneous approach to IEEE Std. 1459 power terms and quality indices

Muñoz-Galeano, Nicolás; Alfonso Gil, José Carlos; Orts-Grau, Salvador; Segui-Chilet, Salvador; Gimeno Sales, Francisco José (Elsevier, 2015-08)

Based on an instantaneous analysis approach to the IEEE Std. 1459, the authors demonstrated in previous works that the effective apparent power should not be calculated including the rms neutral current and the rms line ...
Meaningful resolution of the IEEE Std. 1459 unbalanced power

Orts-Grau, Salvador; Muñoz Galeano, Nicolás; Alfonso Gil, José Carlos; Segui-Chilet, Salvador; Gimeno Sales, Francisco José (Institute of Electrical and Electronics Engineers (IEEE), 2011-08)

This letter present a new resolution of the IEEE Std. 1459 unbalanced power (SU1). The resolution is intended to achieve a better quantification of the power terms included in SU1. The new definitions improve the quantification ...
Measurement system for a power quality improvement structure based on IEEE Std.1459

Alfonso Gil, José Carlos; Orts-Grau, Salvador; Muñoz Galeano, Nicolás; Gimeno Sales, Francisco José; Segui-Chilet, Salvador (Institute of Electrical and Electronics Engineers (IEEE), 2013-12)

[EN] This paper presents an IEEE Std. 1459 power magnitude measurement system working as a part of a power quality improvement structure. It is intended to enhance the performance of selective shunt active power compensators ...
Unbalanced and Reactive Currents Compensation in Three-Phase Four-Wire Sinusoidal Power Systems

Montoya-Mira, Rafael; Blasco Espinosa, Pedro Angel; Diez-Aznar, José-Manuel; Montoya Villena, Rafael; Reig-Pérez, Miguel Jorge (MDPI AG, 2020-03)

[EN] In an unbalanced linear three-phase electrical system, there are inefficient powers that increase the apparent power supplied by the network, line losses, machine malfunctions, etc. These inefficiencies are mainly due ...
