DYNAMIC LOAD MODELING IN TAIPOWER SYSTEM STABILITY STUDIES

Based on the component approach, two kinds of dynamic load models, inc luding a single-motor model and a two-motor model, have been developed for the stability studies of Taiwan power system. The study results a re presented in this paper. Two different events which occurred in the Taipower system have been reproduced by utilizing the derived dynamic load models. One set of field-measurement data, obtained from a three -phase bus-ground fault, is used to evaluate the improvement in accura cy provided by dynamic load models. The other field-measurement dale, obtained from a low frequency oscillation, are used to analyze the eff ect and the sensitivity of dynamic load modeling.
