电能质量监测数据采集分析系统

The Data Acquisition ＆ Analysis System of Power Quality Monitoring

电能质量监测技术是目前电力领域的一个研究热点。电能质量监测的难点是对突变的、暂态的、非平稳状态下电能质量扰动的检测日。本文介绍了一种结构合理并以数字信号处理器（DSP）TMS320VC5402为核心的数据采集分析系统，通过在该电能质量分析平台的DSP上运行扰动分析算法，提取电网节点的扰动情况并记录特征信息。文中主要描述了该数据采集分析系统的硬件设计。实际运行结果表明，该方案具有采样率高、实时性较好和较高的性价比等优点。

At present, the power quality monitoring technique is a researching hotspot in the electric power area. The difficult points of the power quality monitoring technology are the detections of the power quality disturbances of mutational state, transient state and non-steady state. The paper introduces a well-constructed data acquisition and analysis system centered on the digital signal processor （DSP）TMS320VC5402, the system extracts the disturbance situations and records the feature information of the power grid nodes by means of running the disturbance analytical algorithm on the DSP of the power quality analysis platform. The paper mainly describes the hardware design of the data acquisition and analysis system. The results of practical operation show that the scheme is of the advantages of higher sampling rate, better real-time and higher cost performance and so forth.
