Abstract:

Metal halide lamp,a kind of high- intensity gas discharge lamp with the circuit containing the arc, is widely used in stadium lighting.Its negative resistance characteristics bring about harmonic current,and the corre-sponding electronic ballasts,which are the main harmonic sources,also generate a large number of electrical harmonics.In this paper,the piecewise linearization method and the polynomial curve fitting method are used to establish an electrical model of 2500W metal halide lamp and a model of three- level electronic ballasts on PSCAD/EMTDC.The proposed models are then employed to analyze the grid- side harmonic current,and the simulation results are compared with the measured data of the lighting circuits of the venues for Shenzhen 26th Summer Univer-siade.The accuracy of the proposed models is thus verified.
