摘　　要：对实际运行的含有各类谐波及间谐波的电网系统的功率计算方法进行研究,并给出了一套较为完整的解决方案。该方案综合多种功率电能计算方法,并进行方法整合,形成了通用的功率计算理论。仿真结果表明,该方案不仅可以基于频率自适应的方式实现有功功率与无功功率的精确计算,还可以得到基波与各谐波的功率分布,有助于谐波源的辨识,能够更好地服务于无功补偿和系统参数控制,提高电能质量。The paper studies the power measurement methods of the operating power grids with various types of harmonics and inter-harmonics and gives a relatively complete solution,which sums up and integrates a variety of power and energy measurement methods,forming a universal power calculation theory. The simulation results show that this solution can not only achieve accurate measurement of active power and reactive power based on frequencyadaptive technology,but also obtain the power distribution of the fundamental wave and each harmonic,helping harmonic source identification,reactive power compensation,control of system parameters and improvement of power quality.
