This paper deals with the identification of a faulty load bus, in a multi-bus power system, monitoring the inter-harmonic and sub-synchronous inter-harmonic operating point in P-δ plane, depending on passivity model based Gauss-Seidal iteration technique. In this analysis, real power, load angle and bus voltage have been calculated and the shifting of the various operating points in the inter-harmonic...
Power system signals are associated with different types of abnormalities, which generate harmonics of various frequencies. These harmonic components deviates the line admittance matrix used for power flow calculations to some abnormal limits, rendering in erratic behavior of a system when fundamental load flow calculations are used. Also the power delivered to a network becomes erroneous, in presence...
