“…Motivated by these theories, numerous valuable articles have appeared [3][4][5][6][7][8][9][10][11][12][13] although none considers the multivectorial character of apparent power components.…”

“…In this way, the multivector enables separate treatment of the smallest non-active power term which considers only the fundamental component, Emanuel approach [11], and the largest one which includes the imaginary part of the complex scalar and the total complex bivector, Fryze approach [2]. It is remarkable that the quantities proposed in Σ (5) have three basic attributes: magnitude, direction and sense.…”

Abstract-Several approaches have been developed to define the non-active power concept under nonsinusoidal situations in electrical systems. Nevertheless, these contributions do not provide a complete and satisfactory solution to the non-active power reversibility between frequency domain and time domain. This paper presents a non-active power multivector concept, based on an original vector space frequency-domain approach that bridges the gap between both domains. The suggested correspondence can provide a convenient descriptive language to reconcile Fryze's instantaneous non-active power with Budeanu´s deactive-power. To clarify this correspondence, a basis example is considered. IndexTerms-Non-active power, apparent power, instantaneous power, multivector, geometric algebra.

“…The power resolutions, which were proposed by Fryze [2], Shepherd&Zakikhani [3], Sharon [4], Kusters&Moore [5] and Czarnecki [6], are widely recognized and employed for the accurate determination of the maximum power factor achievable with passive compensators and to measure the load's nonlinearity degree under non-sinusoidal conditions. In addition to that, several studies [8]- [11] investigated the physical meaning of these power resolutions via qualitative and/or quantitative analysis.…”

For non-sinusoidal single-phase systems, the classical apparent power has been divided into various components using different techniques. These power resolutions generally aim at to provide a tool for the accurate determination of the maximum power factor achievable with a passive compensator and to measure the load's nonlinearity degree. This paper presents a current decomposition-based methodology that can be employed for computationally efficient implementation of the widely recognized non-sinusoidal power resolutions. The proposed measurement method and the original expressions of the power resolutions are comparatively evaluated by considering their computational complexity. The results show that the proposed method has a significant advantage in terms of computational efficiency for the simultaneous measurements of the powers when compared with the original expressions. Finally, in this paper, a PC-based power meter is developed using the proposed measurement method via the LabVIEW programme.
