| Abstract:With fault-indicators used in distribution network widely, the wireless synchronous communication and low power technology are more important. This paper introduced the feature of fault-indicator, presented a new synchronous technology with high precision and low power base on TPSN of sensor network and round robin algorithm. With system test, this low power synchronous communication can reach synchronous demand, and can satisfy requirement of power dissipation. The reliability of this system technology is improved by actual operation. |
