摘　　要：谐波电能如何科学计量仍是一个值得探讨的问题,判断能否准确计量谐波电能,首先需要谐波发生器,正是基于这样的考虑,文中设计了一种基于FPGA的任意波形发生器的设计方案。系统以FPGA芯片EP4CE115F29C8为核心,并结合Verilog HDL硬件描述语言设计了一种频率、相位、幅度、谐波比例可调的任意波形发生器。该波形发生器适用于IEC 61850标准的数字电能表溯源方法中对数字信号源的要求,同时该波形发生器输出的谐波信号,可模拟电网中的污染源谐波信号,为谐波条件下数字化电能表的计量工作提供了信号源,具有一定的理论研究和实际应用价值。How to scientifically measure the harmonic energy is still a problem that worth exploring,and the accurate measurement of harmonic energy is determined by the harmonic generator,which is the first consideration,on this basis,this paper presents a design scheme of arbitrary waveform generator based on FPGA. The system takes FPGA chip EP4 CE115 F29 C8 as the core and combines Verilog HDL hardware description language to design an arbitrary waveform generator with adjustable frequency,phase,amplitude and harmonic ratio. The digital waveform generator for IEC 61850 standard meter tracing method of digital signal source,meanwhile,the waveform generator outputs signal harmonic,and the polluted harmonic signal sources can be simulated in the power grid,the measurement work for digital power under the condition of harmonic energy meter provides a signal source,which has a certain theoretical and practical research application value.
