摘要：
As special power load exerts large impact on the stability of power system, the power quality and the safety of power equipment, its suitable modeling is essential in power system analysis. With the measured data of ferrosilicon load as an example, the self-varying characteristics of special power load are analyzed. Based on the UPI function of PSASP and user program, the time-varying current injection method is adopted in the modeling of special power load, which represents different electrical characteristics of load in the form of injection currents by circuit calculation. The model of the ferrosilicon load of a region in Ningxia is built according to its measured data, the comparison between simulative curves and measured data verifies the effectiveness and feasibility of the established model.
