电力计量中电力谐波的影响与防范措施

Discussion on the Influence and Measures of Power Harmonics in Electric Power Measurement

在电力系统中,由于各类非线性元件的存在,使得谐波的存在成为必然,同时谐波会加剧电网功耗损失,危害相关设备安全,还会对电力计量产生不利影响,为此谐波的检测及治理也是对电能质量的重要保障。本文重点分析了电力谐波对计量所产生的影响,并对电力计量如何规避谐波干扰提出相关措施,以作参考。

In the power system,due to the existence of various non-linear components,the existence of harmonics is inevitable.At the same time,harmonics will aggravate the loss of power consumption of power grid,endanger the safety of related equipment,and also have adverse effects on power metering.Therefore,the detection and treatment of harmonics is also an important guarantee measure of power quality.In this paper,firstly,the power harmonics and their measurement methods are briefly described,focusing on the analysis of the impact of power harmonics on the measurement,and how to avoid the harmonic interference of power measurement measures,for reference.
