摘　　要：提出一种三相谐波电流全数字化快速提取算法和检测装置。通过采用实时性较高的基于瞬时无功理论的谐波检测原理,并辅以三相数字锁相技术和无限冲击响应的数字滤波技术,构成了完整的三相谐波电流全数字化快速提取算法。与此同时,开发了一套基于浮点DSP TMS320F28335的主从式双DSP+CPLD及外扩16位高精度采样单元的硬件检测装置,以保证能够实时地实现该算法。样机试验结果验证了设计的有效性。A three-phase harmonic current detector based on pure digital signal processing technology is proposed,which adopts the harmonics detection principle based on instantaneous reactive power theory with better real time performance.The three-phase digital PLL and IIR lower-pass digital filters are designed to realize the quick extraction algorithm of three-phase harmonic current.To ensure the better real time performance,master-slave type dual DSP＋CPLD configuration is applied with the float point DSP TMS320-F28335 and an additional highly accurate 16-bit sampling unit.The experimental results of the prototype show the design is effective.
