Abstract: Aiming at the shortcomings of the existing electric energy metering method, combining with the harmonic responsibility analysis model based on the reference impedance method and the idea of apparent power decomposition in IEEE Std 1459-2010 standard, two new metering indicators—billing active power and billing power factor are defined. A new electric energy metering method is proposed and its specific implementation steps are given. The simulation model is built in Matlab/Simulink, and three different examples are set up. Using the simulation data, the various metering indicators need to be examined by the existing electric energy metering method and the new electric energy metering method are calculated. The calculation results show that the new electric energy metering method not only overcomes the shortcomings of the existing electric energy metering method, but also is very easy to be popularized and applied.
Key words: electric energy metering; harmonic responsibility; billing active power; billing power factor

摘要:针对现有电能计量方法的缺点, 结合基于参考阻抗法的谐波责任分析模型和IEEE Std 1459-2010标准对视在功率的分解思路, 定义了两个新的计量指标—计费有功功率和计费功率因数, 提出了一种新的电能计量方法, 并给出了它的具体实现步骤。 在Matlab/Simulink中搭建仿真模型, 设置了三个不同的算例。 通过仿真数据计算出了现有电能计量方法与新电能计量方法所需考核的各个计量指标。 计算结果表明, 新电能计量方法不仅改进了现有电能计量方法的缺点, 而且非常易于推广和应用。
