摘要

摘要: 为解决非线性动态负荷条件下，智能电能表的动态误差测试问题.本文首先将m序列算子作为映射算子，采用基于信号特性建模的方法，建立三相畸变波形m序列动态测试信号结构化参数模型.其次根据压缩检测（Compressed measurement，CM）理论，采用系统稳态优化的方法构造最优压缩检测测量矩阵，实现对动态测试功率信号电能量值的检测.仿真实验表明，压缩检测方法可以对畸变波形m序列动态测试信号进行电能量值的检测，检测算法的相对误差优于1×10^-13.

Abstract: To solve the problem of dynamic error measurement of smart energy meter under nonlinear dynamic loading conditions, firstly, we consider the m-sequence operator as a mapping operator and establish a structural model of three-phase distortion waveform m-sequence dynamic test signal using the method base on the load features. Then, according to compressive measurement, we construct the optimal measurement matrix by means of system steady-state optimization to realize the electrical energy measurement. Finally, numerical simulations are performed to prove the reliability of the compressed measurement (CM) method, the relative errors of the measurement algorithm being superior to 1×10^-13.
