谐波对电能计量的影响及其对策探讨

To Investigate the Effect of Harmonics on Power Metering and Countermeasures

电能计量如果受到谐波的影响,其计量的准确性将会大大降低。谐波会对电能计量装置造成一定的影响,而谐波又是电力系统中不可消除的因素,于是,如何降低谐波对电能计量的影响便成为供电企业面临的一项重要课题。分析了谐波对电能计量的影响,并提出相应的改进措施,以供参考。

If you are affected harmonic energy measurement, accuracy of its measurement will be greatly reduced. Harmonic energy metering device would have been affected, but also is a factor harmonic power system can’t be eliminated, then, how to reduce the effects of harmonics on the energy measurement of power has become an important issue facing enterprises. The influence of harmonics on power metering and propose appropriate measures for improvement, for reference.
