频率偏移对数字化电能表计量误差影响分析

数字化电能表的检定规程及相关标准正在制订中,为对相关技术标准的技术指标规定提供参考,加强数字化电能表的质量管控,在数字化电能表测试项目研究的基础上,文章对现场运行工况中频率偏移对数字化电能表不同算法进行了仿真研究,对不同型号电能表计量性能产生的影响进行了测试试验,试验结果显示频率偏移对电能表几乎无影响。

Research on influence of frequency deviation on digital input electricity meters

At present, the verification regulation and relevant standards of digital input electricity meters are standardiz-ing. With regard to provide reference to technical indicators of relevant standards and to strengthen quality control of digital input electricity meters, this paper researched simulations on influence of frequency deviation to different kinds of algorithms in digital input electricity meters. Experiments of different types of digital input electricity meters influ-enced by frequency deviation are conducted in the laboratory. The experimental result indicated frequency deviation can hardly influence meters when adopted optimization algorithm.
