摘要 IEC闪变仪作为闪变强度测量的国际标准被广泛接受。但存在对高频间谐波造成的闪变不能测量的缺陷。文章根据IEC闪变仪的工作过程分析了导致这种缺陷的原因,并基于白炽灯的热平衡方程及其热辐射发光特性,建立了能反映间谐波电压影响的白炽灯光通量表达式,进而提出了闪变仪的改进模型。模型的计算机仿真结果与实验结果的比较表明,改进的白炽灯闪变仪模型能有效地克服IEC闪变仪的缺陷。 IEC flickermeter has been widely accepted as an international standard for flicker severity measurement. But it is unable to measure flickers caused by high frequency interharmonics. This paper analyzes the cause of the problem. Based on the heat balance equation and thermal radioluminescence characteristics of incandescent lamp, the equation of luminous flux of lamp that can express the impact of interharmonic is established and an improved flickermeter model is proposed. Comparison between computer simulation of models and lab experiment results show that the improved flickermeter model can overcome the IEC flickermeter deficiency effectively.
