摘要
针对电网谐波污染问题,通过简要分析目前谐波检测设备存在的不足,提出了一种采用专用电能测量芯片CS5451以及嵌入式系统作为平台实现谐波检测的系统,就存在的零点漂移误差给出了相应的补偿算法,设计了利用GPRS网络实现设备节点间数据传输的通信协议。实验结果表明,该方案提高了谐波检测系统的精度,实现了检测设备节点间的信息交互,为谐波检测的实施提供了便利。
To solve the problem of harmonic pollution in power grid,based on analysing harmonic detection devices at present,a harmonic detection system is proposed,which adopts CS5451 for energy measurement chip and the embedded platform is proposed,and the compensation algorithm to zero drift error is introduced.The communication protocol to realize the data transmission by using GPRS network is designed.Under the above method not only improved the precision of detection system,but also realized the information interaction between devices.It facilitated the implementation to harmonic detection.
