METHOD FOR CONTROLLING PARALLEL ACTIVE FILTER FOR DISTURBED NETWORKS AND ASSOCIATED ACTIVE FILTER

摘要

The invention relates to a method for controlling a parallel active filter adapted to filter an unbalanced and / or disturbed electrical network comprising a source (1) of supply voltage and a load (7) non-linear connected to the source ( 1) by a set of supply wires comprising n supply wires, with n ≥ 1, connected to the load at n common coupling points, and a neutral wire, comprising a step of injecting current, said injected current, by the active filter into each wire of the set of supply wires so that the nonlinear load (7) is fed by a total current sum of the current delivered by the source ( 1) power supply and the injected current. The control method is characterized in that the injected current ir in each supply wire of the set of supply wires is equal to:
