| 摘 要： | 从无功功率定义出发,经严格的数学公式推导,提出了一种在正弦条件下能同时实现有功功率和无功功率测量的方法,给出了实现其测量方法的电路原理框图,对测量误差及其影响量进行了动态分析,给出非线性误差的计算公式.该方法使有功、无功测量电路合一,降低了应用电路成本,提高了测量电路的可靠性.

| Abstract: | This paper, based on the principle of the reactive power, introduces a mathematics expression- proved method which can realize the simultaneous measurement of the active power and reac- tive power in the sine condition and offers the circuit principle block diagram which realizes the measurement method. This paper also analyzes the measurement error and its influence and gives the calculation expression of the linearity. |
