A New Approach to Compensation of Instantaneous Inactive Power

Abstract

The theory of the instantaneous three-phase powers have been developing in different ways. The zero sequence components of the load affect the source during the process of instantaneous inactive or reactive power compensation. Different 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 effects of the zero sequence components on the source currents, extending the new approach to all unbalanced systems.
