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 apparent power extends, and adapts for new electrical conditions, the procedure applied by IEEE Std. 1459 for the quantification of active and reactive power in single-phase systems.
This proposed approach is based on the analysis of per-phase and three-phase instantaneous power flows when a three-phase four-wire balanced non-linear load is connected to an ideal power network that supplies a set of positive-sequence fundamental voltages. The per-phase and three-phase instantaneous power flows caused by positive-, negative-, and zero-sequence harmonic load currents are analyzed. The results obtained for the load zero-sequence harmonic currents disagree with the results obtained when applying IEEE Std. 1459. As a consequence, a new definition of the effective quantities is proposed. A comparison between the new definitions and IEEE Std. 1459 definitions is made in the paper. [-]

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 ... -
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.

Effect of wind turbine converter control on wind power plant harmonic response and resonances
Sainz, Luis; Monjo, Lluís; Pedra Durán, Joaquín; Cheah-Mane, Marc; Liang, Jun; Gomis-Bellmunt, Oriol The Institution of Engineering and Technology (2017-02)Wind turbine harmonic emissions due to power electronics are a well-known power quality concern in wind power plants (WPPs). This problem may be increased by resonances because they amplify harmonic distortion around ...
