摘要
介绍了一种基于ATT70228B电能计量芯片的配变监控终端的设计方法。系统以单片机AT89S52为控制核心，ATT7022B采集电能参数，GPRSDTU传输数据，实现对变压器的电流电压值、有功功率、无功功率、电能、功率因数等参数的实时监控，保证电网的安全运行。
The paper introduces a design of Transformer Terminal Unit based on ATT7022B IC. Combining with SCM AT89S52 as the controlling core, the electric power parameters＂ collection by ATT7022B IC and the data transmission in use of GPP,.S DTU, it realizes the transformer＂ s monitor of current and voltage value, active power, reactive power, energy and power-factor, which ensures the security of power grid.
