| Abstract: |
| Taking current differential protection WXH-803 as an example,the optical fiber com-munication system of HV(High Voltage) line protection is analyzed,especially the communication system architecture of special optical fiber channel mode,64 Kbit / s multiplex mode and 2 Mbit / s multiplex mode.Different influences on optical fiber communication performance under above three communication modes are studied,including the clock mode of optical terminal and mul-tiplex equipment,the optical receiving power,the optical transmitting power,the optical saturation power,the margin of communication channel,the electromagnetic-shield manners,the equipment match and so on.The channel connection status is introduced,and general problems in optical fiber communication system for relay protection and simple countermeasures are summarized. |
