TASK Power Model Based Dynamic Error Testing for Electricity Meter

该文首先采用连续空间函数序列的信号分解方法,建立了动态测试电压、电流和功率的函数序列模型。其次,提出了一种面向时间过程的三幅值键控(ternary amplitude shift keying,TASK)动态测试功率模型,给出了TASK动态功率的产生方案;在此基础上,定义了单向与双向功率的多种动态负荷模式。最后,基于所提出的理论方法,搭建了电能表动态误差测试系统,测试了国内外不同厂家多种电能表的动态误差,验证了TASK动态测试信号模型与测试方法的正确性。

Using the signal decomposition method of function sequence in space of C, we established dynamic test voltage, current and power function sequence models. Then a time-process oriented model of ternary amplitude shift keying（TASK） dynamic testing power was proposed, which given a TASK dynamic power generation plan. Based on the TASK power model, a variety of dynamic power modes both in uni-directional power and bi-directional power were proposed. Finally, a dynamic error testing system of electricity meters was constructed. Some electricity meters from different manufacturers are tested in the provided testing system, and the test results were given.
