| 摘要: |
| 根据电能质量分析的实际需要,给出基于浮点数字信号处理器TMS320C6713的电能质量分析仪的硬件整体实现方案及软件设计思想。着重介绍了DSP核心处理模块TMS320C6713的功能、特点及设计开发思路。有源滤波模块滤除50次以上的高次谐波,减少了高次谐波的影响;16位的AD则保证了采样的高精度;以太网端口可以方便对不同区域电能质量的综合监测。此外,还介绍了数字电源及模拟电源分开的电源设计方案。最后,对如何利用USB2.0与PC机进行实时波形显示、设备故障录波、间谐波分析等功能拓展进行了探讨。 |

| Abstract: |
| According to the practical requirements of electric power quality analysis,the overall hardware implementation scheme and software design idea of an electric power quality analysis equipment are proposed,which are based on the float digital signal processor TMS 320 C 6713. The functions and characteristics of DSP,as well as the concept of development,are introduced. Active filter filters 50 th and above harmonics to reduce their influences;16 - bit AD guarantees high precision;and the Ethernet ports facilitate the integrated supervision and test of different areas. The design scheme of power supply which separates digital power supply from analog power supply is also introduced. The function extension is discussed,such as the real - time waveform display,fault wave recording,inter - harmonics analysis and so on with USB 2.0 port and PC. |
