Abstract

The harmonic detection method based on(p - q - r)defines the instantaneous power of zero-order current under the new spatial coordinate system, which can eliminate the midline current independently. This paper introduces the principle of the detection method and puts forward the(p - q - r)method of harmonic detection without voltage sensors. The capacitive midpoint active filter is modeled and simulated to prove that when the voltage of the grid is unbalanced and distorted, the method based on(p - q - r)do not require a voltage sensor to accurately carry out harmonic detection and fully compensate for the current harmonic components.
