Prof. Leon Tolbert (The University of Tennessee, USA) made a presentation entitled Active Filter Implementation Using a Generalized Reactive Power Theory at the invitation of Institute of Power Electronics in Electrical Engineering Building on Apr.1st.
This presentation presented a generalized nonactive power theory, in which the instantaneous currents (active and nonactive) and instantaneous powers (active and nonactive) were defined. This theory was implemented in a parallel nonactive power compensation system. The theory was valid if the system was three phase or single-phase, sinusoidal or non-sinusoidal, periodic or non-periodic, balanced or unbalanced. The simulation and experimental results not only verified the validity of the theory, but also showed that this theory could perform instantaneous nonactive power compensation with fast dynamic response.
