Abstract :
Many authors have identified the need to improve the definitions of non-active power under nonsinusoidal conditions. This paper proposes a solution where the total instantaneous power is decomposed into active and non-active components based closely on the power system properties. The new theory presented is an attempt to achieve this decomposition for the single-phase system. This theory is based on voltage and current harmonic components. The theory is evaluated, for linear and non-linear loads in the presence of harmonics. Evaluation of the results demonstrates good performance of the proposed theory. With the active/non-active power components obtained from the definitions of the theory, an accurate measurement, especially of the non-active power, is achieved. The non-active component can also be utilised to achieve optimal compensation
