خلاصه مقاله:

The theory of the instantaneous threephase powers have been developing in di®erent ways. The zero sequence components of the load a®ects the source during the process of instantaneous inactive or reactive power compensation. Di®erent approaches have been used to overcome this issue, such as Clark transformation to separate zero sequence components from the phase quantities. This paper introduces a new approach to a previously proposed theory of the instantaneous reactive power compensation, minimization method. The proposed method is applicable to all balanced three-phase systems as well as unbalanced system without zero sequence components. A separate paper discusses a new way of overcoming the e®ects of the zero sequence components on the source currents, extending the new approach to all unbalanced systems.
