摘要
为提高电能采集的精确度,确保配电系统的安全经济运行,本文设计了一款改进型电力监测终端。采用三相多功能高精度计量芯片ADE7880采集多种模式下的电能信息,通过GPRS-DTU模块与用电管理中心服务器进行数据的双向通信,并对TEA通信加密算法进行改进,确保了系统通信数据的安全性。通过实际测试,将采集到的不同模式下的电流、电压、谐波、功率等电力参数通过无线终端上传到用电管理中心服务器,其精度已满足配电网安全经济运行的要求。
In order to improve the accuracy of electric energy acquisition and to ensure the safe and economical operation of distribution system, an improved power monitoring terminal is designed.Three phase multi-function high-precision measurement chip ADE7880 acquire electric power information under various modes. Bidirectional communication between data is finished from the GPRS-DTU module and a power management center server and improve the TEA communication encryption algorithm to ensure the security of the system communication data. Through the actual test, the current, voltage, harmonic, power and other power parameters in different modes are uploaded to the power management center server through the wireless terminal. Its accuracy has reached the requirements of the safety and economic operation of the distribution network.
