摘要
由于谐波电能的反向流动会造成电能表计量结果小于负载从电网中吸收的基波电能,而且现行的计量方法是把这部分电能从电网中吸取的基波电能中部分或全部扣除,所以是一种不合理的计量方式。对此,提出了相应的解决方法和对策。最后,仿真分析电能计量误差。通过谐波对电能计量影响的分析,提出了一种改进的、较为合理的电能计量方式。
As the reverse flow of the harmonic energy makes the results of electric power measurement smaller than fundamental wave energy which were deducted from the absorbed fundamental energy of the grid partly or all according to the current measurement. This is an unreasonable way of measurement. The corresponding solutions and countermeasures were put forward. Finally, the error of electric power measurement was simulated. Through analysis of the influence of harmonic on electric power measurement, a reasonable improvement method was put forward.
