摘要: 金属卤化物灯在场馆照明领域广泛应用,这种高强度气体放电灯电路本身含有电弧,它的负阻特性产生谐波电流,与其配合使用的电子镇流器也产生大量谐波,成为了主要的谐波源.文中分别采用分段线性拟合和多项式曲线拟合的方法在 PSCAD/EMTDC 上建立了2500W 金卤灯以及三级电子镇流器的模型,分析模型运行时电网侧的谐波电流情况,并将仿真结果与深圳大运会体育场馆照明回路的实测数据进行对比,验证了模型的准确性.

关键词: 金卤灯, PSCAD/EMTDC, 电子镇流器, 谐波

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.
