Abstract
In the process of developing power RTU by using Zynq-7000 series FPGA,the effective value of AC signal voltage current should be calculated in collecting telemetry information.This paper discusses measurement of the effective value through the use of modularization-based design methods and a series of Xilinx IP core.Firstly,the frequency of the input signal was calculated by digital zero-crossing method.Then RMS of the signal was calculated through integrated method.The measurement of remote communication data had certain errors as actual frequency of signal fluctuated in small scope with the changes of electrical load.And error compensation was realized by the analysis of error condition of calculation to improve the measurement accuracy of the effective value of the AC signal voltage current.Finally,IP core was made by setting interrelated parameters.Matlab and FPGA simulation results were verified consistent.关键词
