Overview of the Instantaneous Reactive Power Theory in Three-Phase Systems

摘要

The wide application of power electronic equipment results in severe non-sinusoidal phenomena, making the conventional steady-state reactive power theory no more applicable. In order to deal with the harmonic compensation and power factor correction under the non-sinusoidal condition, scholars have carried out lots of research works. This paper discusses and compares several commonly used instantaneous reactive power theories, and pointes out the relationships and differences of them. The work of this paper contributes to better understanding of the instantaneous reactive power theories.
