摘要
为了提高变电站远动专线通道的检修效率,研制了一种变电站远方通道切换装置。该切换装置内置在调制解调器中,当远动专线通道中断时,在调度主站端可遥控启动切换装置,实现远方切换站端调制解调器,使远方恢复远动专线通道的通信成为可能。通过现场试点应用验证该装置的有效性,应用效果表明:该装置能正确、可靠地实现主备通信通道的切换,极大地缩减通信通道中断时间,提高了远动系统运行可靠性。
In order to improve the maintenance efficiency of the telecontrol line channel in substations,a substation remote channel switching equipment which is assembled into a modem is developed.When the telecontrol line channel was interrupted,the switching equipment can be started remotely at the dispatching master station.The switching of the station modem can be realized remotely,making it possible to recover the communication of the telecontrol line channel remotely.The effectiveness of the equipment has been testified by field trial application.The application results show that this equipment can correctly and reliably realize the switching between the main and backup channels,which greatly reduces the time of communication interruption and improves the operation reliability of the telecontrol system.
