Phase Identification Algorithm and Test Data

Abstract

MATLAB Function: function [exitflag] = UCRPI(V_ref,V_unknown)

Input Arguments: Three-phase voltage magnitude at reference node and unknown node (3*N matrices)

Output Arguments: One of the following configurations, based on the results of the algorithm: Configuration 1: A = a B = b C = c Configuration 2: A = a B = c C = b Configuration 3: A = b B = c C = a Configuration 4: A = b B = a C = c Configuration 5: A = c B = a C = b Configuration 6: A = c B = b C = a

Assumption 1: 1st, 2nd, and 3rd row of V_ref denotes phase A, B, and C of reference node Assumption 2: 1st, 2nd, and 3rd row of V_unknown denotes phase a, b, and c of unknown node

Use the following MATLAB code to call the UCRPI function:

load V_ref_test.mat; load V_unknown_test.mat; % set es to be the start time % set ed to be the end time V_ref = V_ref_test(:,es:en); V_unknown = V_unknown_test(:,es:en); exitflag = UCRPIVMCv1(V_ref,V_unknown);
