摘要：

This paper presents first a review of the conventional active and reactive power theory, valid for the steady-state analysis and them the instantaneous power theory, introduced by Akagi et al [1, 2], is presented. This instantaneous theory is, valid for steady-and-transient states and for generic voltage and current waveforms. Some examples explaining the physical meaning of the new concepts will be presented. Also, by using the well known concepts of symmetrical components together with the new theory the powers in an unbalanced system will be analyzed, including the zero-sequence instantaneous power. It will be presented an example showing how this theory can be used to design and control an active power filter. Some simulation results are presented and discussed.
