Parallel Association of Shunt Active Power Filters [PDF]

open access: yes2007 IEEE International Symposium on Industrial Electronics, 2007
This paper describes different types of parallel association of Shunt Active Power Filters, presents computer simulation models developed in PSCAD®/EMTDC?, and shows simulated results for each case. The control system used in the active filters is based on the Instantaneous Reactive Power Theory (p-q Theory). The active filters use periodic sampling as
