电能表动态误差特性实验研究

摘要

针对电能表的动态误差测试问题，建立了OOK动态负荷信号的模型和电能表动态误差测试系统，提出了暂态、短时、长时三种模式和九种模态的测试激励信号，提出一种电能表动态误差的计算方法，对国内三个厂家的电能表进行了动态误差性能的实验研究，给出了实验结果。%In order to research the dynamic error characteristic of electrical energy meter, a model of OOK dynamic load signal and a testing system of electrical energy meter’s dynamic error are proposed in this paper. It introduces three models (transient, short-time and long-time dynamic models) and nine modes of testing excitation signal and an experimental measure method of electrical energy meter’s dynamic error. After the dynamic error testing research for electrical energy meters from three domestic manufacturers, the experimental results are given in the paper.
