摘要
运用调制理论,对自激式电子镇流器荧光灯在间谐波导致的闪变电压下的功率波动进行理论分析,得到了在电源电压中含间谐波分量时荧光灯的功率响应,建立了荧光灯瞬时功率波动特征与间谐波特征之间的关系曲线。利用Matlab/Simulink软件对该研究对象进行的仿真和实验研究,验证了理论分析结果的正确性。理论分析和实验结果均表明电源电压中的间谐波分量可能导致荧光灯闪变,且闪变频率与间谐波造成的电压波动频率相同。荧光灯瞬时功率波动特征与间谐波特征之间关系的建立,有助于进一步对荧光灯在间谐波电压条件下的闪变效应进行评价方法研究,及其间谐波闪变限制标准的制定。
Based on modulation theorem,theoretical study was carried out to obtain the input power fluctuation of the fluorescent lamp（FL） with self-oscillating electronic ballast supplied by voltages including interharmonics.And the relationship between characteristics of FL＇s instantaneous power fluctuation and interharmonics is established.The simulation and experimental results confirm that the proposed methods are valid.Both theoretical and experimental results show that the interharmonic component included in supply voltage indeed leads flicker of FLs and the flicker frequency equals the voltage fluctuation frequency caused by interharmonics.The established relationship between FL＇s instantaneous power fluctuation and interharmonics is helpful to further research on the evaluating flicker effect of interharmonics on FLs and framing the flicker limit standard of interharmonics.
