Abstract：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.
