INHERENT STRUCTURE-THEORY OF NETWORKS AND POWER-SYSTEM HARMONICS

The inherent structure theory of networks, already applied in the lite rature at the fundamental frequency to a variety of planning problems, is extended to the field of power system harmonics. In the context of this theory, the harmonic admittance matrices are reformulated in ter ms of their eigenvalues and eigenvectors, showing that these expansion s can be useful to create a framework in which the power system respon se to harmonic disturbances can be better understood. After the presen tation of the theoretical background, some power system harmonic probl ems are tackled to show possible applications of this theory. Numerica l experiments on a 17-busbar distribution system give evidence of the significance of application to the field of power system harmonics.
