    • closedAccess   Discussion on Useless Active and Reactive Powers Contained in the IEEE Standard 1459 

      Orts-Grau, Salvador; Muñoz Galeano, N.; Alfonso, j. Carlos; Gimeno Sales, Francisco José; Seguí Chilet, Salvador IEEE (2011)
      This paper deals with the useless active powers and the reactive powers included in the unbalance power (SU1), and in the nonfundamental effective apparent power (SeN) defined in IEEE Standard 1459. Only the fundamental ...

    • closedAccess   Enhanced Grid Fundamental Positive-Sequence Digital Synchronization Structure 

      Alfonso, j. Carlos; Vague Cardona, José Joaquín; Orts-Grau, Salvador; Gimeno Sales, Francisco José; Seguí Chilet, Salvador Institute of Electrical and Electronics Engineers (IEEE) (2013-01)
      The second-order generalized integrator (SOGI) filter and delayed signal cancellation (DSC) structures have been used separately in order to improve the synchronization systems response in adverse grid conditions. Taking ...

    • closedAccess   Improved Shunt Active Power Compensator for IEEE Standard 1459 Compliance 

      Orts-Grau, Salvador; Gimeno Sales, Francisco José; Abellán García, A.; Seguí Chilet, Salvador; Alfonso, j. Carlos IEEE (2010)
      This paper presents the simulated and experimental results of an improved shunt active power compensator (SAPC). The proposed power compensator achieves IEEE Standard 1459 compliance by using moving-window discrete Fourier ...

    • closedAccess   Instantaneous approach to IEEE Std. 1459 power terms and quality indices 

      Muñoz Galeano, N.; Alfonso, j. Carlos; Orts-Grau, Salvador; Seguí 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 ...

    • closedAccess   Meaningful Resolution of the IEEE Std. 1459 unbalanced power 

      Orts-Grau, Salvador; Muñoz Galeano, N.; Alfonso, j. Carlos; Seguí Chilet, Salvador IEEE (2011)
      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 ...

    • closedAccess   Measurement System for a Power Quality Improvement Structure Based on IEEE Std.1459 

      Alfonso, j. Carlos; Orts-Grau, Salvador; Muñoz Galeano, N.; Gimeno Sales, Francisco José; Seguí Chilet, Salvador Institute of Electrical and Electronics Engineers (IEEE) (2013-12)
      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 ...

    • closedAccess   New Resolution of the Unbalance Power According to Std. 1459 

      Orts-Grau, Salvador; Alfonso, j. Carlos; Gimeno Sales, Francisco José; Seguí Chilet, Salvador IEEE (2010)
      Harmonic distortion and load unbalances have been an important issue in the last few years, motivating a large number of studies in active power compensators used for the power network quality improvement. Following an ...

    • closedAccess   Non-fundamental effective apparent power defined through an instantaneous power approach 

      Muñoz Galeano, N.; Alfonso, j. Carlos; Orts-Grau, Salvador; Seguí Chilet, Salvador; Gimeno Sales, Francisco José Elsevier (2011)
      This paper proposes a new definition of non-fundamental effective apparent power based on an analysis of instantaneous power flows. This new instantaneous power approach for the calculation of the non-fundamental effective ...

    • openAccess   One-Cycle Zero-Integral-Error Current Control for Shunt Active Power Filters 

      Orts-Grau, Salvador; Balaguer, Pedro; Alfonso, j. Carlos; Martinez Marquez, Camilo Itzame; Gimeno Sales, Francisco José; Seguí Chilet, Salvador MDPI (2020-11-26)
      Current control has, for decades, been one of the more challenging research fields in the development of power converters. Simple and robust nonlinear methods like hysteresis or sigma-delta controllers have been commonly ...
