Design of Harmonic Energy Meter Based on TDK+DSP+MCU

摘要：

To meet the urgent demand of electric power industry on harmonic energy measurement, one kind of three-phase multifunctional harmonic energy meter structure composed by TDK71M6515H+ADSP-BF531 +PIC32MX460F512L is presented. The operating principle of electric energy meter is described. Besides, the data acquisition circuit based on TDK71M6515H and the data processing circuit with the core of ADSP-BF531 are introduced in details. Furthermore, correction methods of ratio error and phase error of harmonic energy measurement and temperature compensation are discussed. Finally, Three-phase harmonic energy meter based on the algorithm proposed has its error of fundamental active power measurement lower than 0.2％, error of fundamental reactive power measurement lower than 1％, amplitude error of harmonic electric voltage lower than 2％, amplitude error of harmonic electric current lower than 5％, and phase angle error between harmonic voltage and electric current lower than 5°. Above data results meet the accura cy requirement of the A class harmonic measurement instruments according to GB/T-14549-93.
