谐波是影响电能计量装置运行准确性与稳定性的重要因素之一,传统的谐波检测方法因存在耗时长、准确率低等问题,并不适宜用于当前高负荷运行的电气化铁路牵引站中。因此,文章对电能计量装置运行误差的谐波来源及自动检测进行了具体的分析,从电能计量装置运行中谐波的来源出发,阐述谐波带来的负面影响,并结合现阶段自动检测技术与方法理论,提出完善的谐波误差检测方式方法,以便降低电能计量装置的运行误差。

Harmonic is one of the important factors affecting the operation accuracy and stability of electric energy metering devices.Traditional harmonic detection methods are not suitable for current high-load operation of electrified railway traction stations due to problems such as long time-consuming and low accuracy.in.Therefore,the paper makes a detailed analysis of the harmonic source and automatic detection of the operation error of the energy metering device.From the source of the harmonics in the operation of the energy metering device,the negative effects brought by the harmonics are described,and the automatic detection technology is combined with the current stage.With the method theory,a perfect harmonic error detection method is proposed to reduce the running error of the energy metering device.
