摘要

This paper proposes a distributed active filter system (DAFS) for alleviating the harmonic distortion of power systems. The proposed DAFS consists of multiple active-filter units (AFUs) installed on the same location or different locations within the power system. Each individual AFU functions like a harmonic conductance to reduce voltage harmonics. A droop relationship between the harmonic conductance and the voltampere (VA) of the AFU is programmed into the controller of each unit, so multiple AFUs can share the workload of harmonic filtering without any communications. The slope of the droop is determined by the VA rating of the AFU in order to distribute the harmonic filtering workload in proportion to the rated capacity of each unit. The principle of operation is explained in this paper, and test results based on a computer simulation and laboratory test bench are provided to validate the functionalities of the proposed DAFS.
