| Abstract: | Aimed at accurately measuring AC electric parameters,this paper introduces the design of the measurement system of AC electric parameters,based on the hardware synchronous sampling measurement,proposes a novel method for measuring reactive power and frequency,and presents the math expression designed for translating linear frequency into DC voltage,and the expression of theoretical error of the frequency measurement.The analysis of the system error derived from the measurement system of AC electric proves that the measurement system promises to accurately measure AC electric parameters. |
