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 ...
An Indirect Procedure for Real-Time Monitoring the Neutral Conductor Deterioration in Three-Phase Distribution Networks

León-Martínez, Vicente; Montañana-Romeu, Joaquín; Peñalvo-López, Elisa; Leon-Vinet, Amparo; Cano-Martínez, Jorge (MDPI AG, 2023-04)

[EN] An indirect procedure for real-time monitoring the neutral conductor condition in threephase distribution networks, based on watching over the growth of a novel parameter (Dt), has been described in this paper. The ...
Effects of the Selected Point of Voltage Reference on the Apparent Power Measurement in Three-Phase Star Systems

León-Martínez, Vicente; Montañana-Romeu, Joaquín; Peñalvo-López, Elisa; Álvarez, Carlos (MDPI AG, 2020-02)

[EN] The phenomenon responsible for the different apparent powers measured in a subsystem of a three-phase star-configured system, based on the voltage reference point, was identified in this paper using specific components ...
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 ...
Four-Wire Delta Service Sinusoidal Operation and Compensation Simulator

León-Martínez, Vicente; Montañana-Romeu, Joaquín; Radda, Peter; Cazorla Navarro, Antonio (MDPI, 2015-10)

An off-line simulator based on Excel used to evaluate the operation of four-wire delta (4WD) services as well as the effects of reactive and imbalance compensators in sinusoidal steady-state conditions is described in this ...
Measurement of power effects caused by the deterioration of the neutral conductor in three-phase distribution networks

Peñalvo-López, Elisa; Leon-Vinet, Amparo; León-Martínez, Vicente; Montañana-Romeu, Joaquín; Valencia-Salazar, Iván (Elsevier, 2022-11)

[EN] The expressions of the powers that measure the effects of the energies manifested by the deterioration of the neutral conductor in low-voltage distribution networks are developed in this paper with the name of ...
Relationship between Buchholz's Apparent Power and Instantaneous Power in Three-Phase Systems

León-Martínez, Vicente; Montañana-Romeu, Joaquín; Peñalvo-López, Elisa; Valencia-Salazar, Iván (MDPI AG, 2020-03-05)

[EN] Similarly to how Steinmetz developed his theory of alternating current in single-phase sinusoidal systems, a few formal relationships between expressions of the instantaneous and Buchholz's apparent power in three-phase ...
