| Abstract: | The fact that most of the power systems are in unbalanced state, this article explains how to make improvement of harmonic detection means based on instantaneous reactive power theory and also tells us how to adopt the closed-loop detection means based on instantaneous reactive power theory to enhance the robustness and stability. Emulation experiment result proves this means has the practicality and feasibility. |
