基于DSP和ARM的电能质量监测系统设计与实现

电能质量问题严重影响电力系统的安全稳定性和经济性。传统的电能质量监测手段存在明显的局限性。针对电能质量重要性的日益突出，提出了一种基于DSP和ARM的系统。根据系统的特点，应用简化的TCP／IP协议，利用DSP强大的数据处理能力和高速A／D转换器，可以满足电能质量监测对实时性的要求。利用ARM作为上位机，构成了基于以太网的网络化电能质量监测系统。采用加矩形窗F胛插值算法，仿真计算结果表明，采用该方法得到的幅值和频率都具有较高的计算精度。

Power Quality Monitoring System Design and Realization Based on DSP and ARM

The problem of power quality severely impact on system stability and economy. The obvious deficiencies exit in the traditional power quality monitoring system. To the increasingly power quality system, a system based on DSP and ARM is given in this paper. According to the characteristic of system , applying simplified TCP/IP protocol, making use of DSP powerful data processing Capacity and high-speed A/D converter the system meets the power monitoring requirements of high real-time performance. And it constitutes an ethernet-based network of power quality monitoring syst,em the use of ARM as a PC. For rectangular window FFT interpolation algorithm, simulation results show that the amplitude and frequency have a high level of accuracy using this method.
