提出了由谐波电能计量单元（AD73360L＋ADSP—BF533）、谐波电能主机功能单元（M30624FGPFP）和电源管理3个部分组成的三相多功能谐波电能表的构成方案。介绍了谐波电能主机功能单元的硬件／功能设计、主程序流程图，多功能谐波电能表通信遵循DL／T645—2007规约，给出了通信程序流程图。研制后的多功能谐波电能表实验表明，其性能及功能符合GB／T17883—1999和DL／T614—1997规定，测量准确度达到基波有功测量误差40．2％，基波无功测量误差≤1％，2～21次谐波电压测量误差≤2％、谐波电流测量误差≤5％、谐波相位测量误差≤5°，满足GB／T-14549—93的A类谐波测量仪器要求。
英文摘要：
A three-phase multi-functional harmonic energy meter is designed, composed of measurement board（AD73360L＋ ADSP-BF533）, host function board（M30624FGPFP） and power supply management. The hardware and function design of host function unit and the main flowchart are introduced. The communication protocol observes the DL/T614 - 2007 and the communication flowchart is given. Experiments show that its performances and functions meets the requirements of GB/T17883- 1999, with the measurement error of fundamental active power less than 0.2 %, that of fundamental reactive power 1%, that of 2nd-21st harmonic voltages 2 %, that of harmonic current 5%, and that of phase angle 5%. It meets the accuracy requirement of the harmonic measurement instruments of class A according to GB/T - 14549 - 93.
