Discussion on Reliability of Narrow-band TD-LTE Network Transmission for Distribution Automation System

In Guangzhou, there is a poor communication between power control systems in equipment rooms and the 100,000 distribution terminals scattered around the city. Guangzhou Power Supply Co.Ltd. (CZPS) planned to upgrade smart power distribution grid with wireless communications technology. It built an integrated data collection platform and several small-scale test zones to collect and analyze data from a pilot. In the GZPS Communication Laboratory, to confirm the reliability and accuracy, the transmission performance indicator of DTU are compared with different RSRP by using wireless public network (GPRS), 230MHz and 1.8 GHz wireless private network testing system.
