Analysis and measurement of spectrum disturbance carrier communication over MV overhead distribution line

WANG Xiao-yan~1,TANG Xiao-jun~2,LIU Yin-long~1,YE Ya-ying~3,LIU Zhi-wei~3(1.Nanjing Automation Research Institute State Grid Corporation of China,Nanjing,210003,China;2.National Automation Research Institure Electric Power Automation Testing Lab,Nanjing 210003,China;3.Fujian Electric Power Dispatching and Communication Center,Fuzhou 350003,China)  
According to DL/T 790 series standards,especially DL/T 790.31 standard,the measurement of spectrum disturbance of carrier communication over Medium-Voltage(MV) overhead distribution line has been carried out.The results indicate that the spectrum leak of the MV carrier communication device does not interfere with the existed carrier communication system,especially carrier transceiver for relay protection under the 5 W(max) nominal signal output power.
