| 摘 要： | 电压波动和闪变是电能质量的重要指标，其对应国标曾先后两次被修订，但其中关于电压变动限值的规定仍存在歧义和不足。文章主要依据GB12326-2008《电能质量电压波动和闪变》对电压变动限值规定展开讨论，得出了两种不同的电压变动评估方法，通过电弧炉的实际测试数据研究了两种评估方法的差异，得出了科学合理的电压变动限值和评估方法。

| Abstract: | Voltage fluctuation and flicker are the important factors of power quality. The relative national standard has been modified twice, but the provision of voltage fluctuation limit still exist ambiguities and shortcomings. It discussed the provision of voltage fluctuation limit based on GB 12326-2008 Power quality-Voltagefluctuation and flicker, and gave two different evaluation methods of voltage fluctuation. The difference between the two methods was studied through the actual test data of electric arc furnace, and scientific and reasonable voltage fluctuation limits and evaluation method were put forward. |
