| Abstract: |
| Distribution transformer remote monitoring terminal based on DSP TMS320LF 2407A and wireless module GR 47 is designed,which takes DSP as controller and GPRS(General Packet Radio Service)wireless network and Internet as communication channel to transmit teledata for remote monitoring of distribution network operational parameters and states.Several communication manners in distribution transformer remote monitoring are compared and GR 47 wireless module is selected for communication.Hardware circuit is designed to connect GR 47 with TMS320LF 2407A,and the commissioning procedures are described.The terminal has powerful functions of data acquisition and processing,including measurement,harmonic analysis and reactive power compensation and so on.Experimental results show that the terminal has reliable communication and better real-time performance. |
