Design Of Power Quality Analyzer Based On SoC FPGA

Since the advent of the alternating-current generator,we entered the age of electricity,it has become the largest source of energy in the society.The availability of electricity also becomes a defining indicator of how quickly social development is and how civilized it is.The demand for electricity has soared,at the same time,the need of nonlinear load has increased.The power quality problem should be solved urgently and the analysis of electrical energy is one of the most direct and effective ways to solve the problem.A power quality analyzer based on SoC FPGA is designed.Intel SoC consists of HPS and FPGA,HPS is mainly responsible for the control,the realization of the relevant parts of the interface,FPGA is mainly responsible for the interface,large data processing.After introducing the application background and development process of the power quality inspection system,the power quality analyzer based on SoC FPGA is designed.With the quality standard and the quality parameter as the starting point of the problem.The design of power circuit,signal processing circuit,A/D sampling circuit,serial port circuit,displaying circuit and other hardware modules have given in the part of hardware.Based on the above hardware design,the embedded system was successfully transplanted,and the development platform for realizing the software of the system was built.In software design,the development environment and the design process are briefly introduced,the FPGA IP register's configuration,the development of embedded Linux system and QT are achieved in HPS.The experiment makes full use of the performance and characteristics of the FPGA and HPS in SoC.The acquisition of three-phase voltage and current,FIR filtering,frequency analysis,human-computer interface displaying and other functions are successfully realized,which has great reference value and application value for power quality measurement and analysis.
