| 摘 要： | 高频保护收发信机仍然依赖于通过每天人工手动＂通道试验＂检查高频通道及设备运行状况,这对实现变电站无人值守产生了极大的制约。文章通过对ON/OFF方式的传统收发信机优缺点进行对比,并与复用保护载波机FSK方式对比,给出了FSK方式收发信机的理论基础,在此基础上提出了适用于变电站无人值守的收发信机方式,增加远方实时在线监测功能,上报监测结果数据至远方主站,消除无人值守站的监控盲区,实现真正意义的无人值守变电站。

| Abstract: | The status of high frequency （HF） protection transceiver still depends on daily check by manual ＂channel test＂, which seriously restricts the development of unattended substation. The pro and con of the traditional transceiver with ON/OFF mode are discussed and compared with those of multiplexed protection carrier with FSK mode, and the theoretical basis of the FSK mode transceiver is presented, then the mode of transceiver in unattended substation is proposed, the function of remote real-time online monitoring to report monitoring data to the remote master station will eliminate monitoring blind spot in unattended substation. This work is of a great practical significance for real unattended substation. |
