Abstract

To determine the power quality disturbance (PQD) source in distribution network, a novel three-stage automatic location algorithm based on chain table and matrix operation is proposed. Firstly, fast pre-judgment of feeder sub-region of PQD is achieved according to chain table. Secondly, preliminary judgment of the PQD source is realized based on definition and operation of several critical describing matrices, which can be automatically generated with chain table and computer programming. Thirdly, accurate location algorithm is implemented using virtual power quality monitor(PQM) and extended matrices. A case study demonstrated that the proposed algorithm can realize location of PQD sources automatically and has many advantages such as small computational complexity and suitable for computer programming. © 2011 Praise Worthy Prize S.r.l. - All rights reserved.
