| 摘要: |
| 首先建立了一种OOK动态负荷电流信号的数学模型，提出了动态负荷电能序列的数学模型，并定义了动态负荷功率模式，即暂态动态负荷模式、短时动态负荷模式和长时动态负荷模式，基于此推导得出了一种电能表动态误差测量的算法。最后建立了智能电能表动态误差测试系统，对3种电能表进行了测试，结果表明电能表的动态误差与激励的动态负荷功率模式紧密相关，不同电能表的动态误差特性差异较大。 |

| Abstract: |
| A mathematical model of OOK（On-Off-Key） dynamic load current is built，a mathematical model of dynamic load energy sequence is proposed and three dynamic load power modes are defined：transient，short-term and long-term，based on which，an algorithm for measuring the dynamic error of smart energy meter is proposed. A lab system is set and three kinds of smart energy meter are tested. Results indicate that，the dynamic error of energy meter is closely related to the dynamic load power mode of driving and the characteristics of dynamic error are quite different among different energy meter kinds. |
| Key words: smart energy meter errors testing on-off-key dynamic load power mode signal model measurements |
