摘要
谐波检测方法的精度及动态响应速度极大地影响有源电力滤波器的性能。以瞬时无功功率理论的ip-iq电流检测算法原理为基础,给出了在芯片TMS320LF2407下的谐波电流检测方法的具体实现,同时给出了硬件电路原理图及外围电路设计和实现该检测算法的程序框图。通过实验得出实验结果并进行了分析,结果表明了此方法的正确性和有效性。
The active power filter＇s performance was influenced strongly by the accuracy and speed of dynamic response of harmonic detection method.The concrete implementation of harmonic detection method on the TMS320LF2407 was provided based on the ip-iq current detection arithmetic of instantaneous reactive power theory.Also the circuit schematics,the peripheral circuit design and program diagram were given.At last,the experimental result was obtained and analyzed.It indicated the correctness and effectiveness of the detection method.
