【摘要】 传统电能计量手段在非线性负荷条件下存在较大误差;本文根据非线性负荷的功率特性,将基于LMS(Least Mean Square,最小均方)算法的自适应陷波滤波器应用于电能计量领域,提出了一种全新的非线性负荷电能计量实现方案;仿真实验结果表明相对于传统电能计量手段而言,本方案对非线性负荷的计量更加准确与合理。更多还原

【Abstract】 The traditional methods of electric energy metering has larger error under nonlinear load condition.According to the power characteristics of nonlinear load,a kind of adaptive notch filter arithmetic based on least mean square is discussed for electric energy metering of nonlinear load.The simulation experiment result shows this new metering method is more accurate than ordinary ones under the condition of nonlinear load.更多还原
