摘　　要：为适应变电站无人值守运行的需要,必须实现高频通道远方测试功能,代替目前的现场手动测试,保证通道的可靠运行。结合巢湖供电公司的现场实际,对高频保护通道远方测试涉及的关键问题进行了研究和阐述,通过受控站端测控单元控制线路保护的收发信机,实现集控中心对高频通道的手动测试和监控端对通道的自动测试。在集控中心监控系统中开发应用软件,对测试过程进行监控和判断,并将测试结果以告警形式通知运行人员,上送调度中心。该系统使用方便、界面友好、结果清晰,有助于提高线路高频保护运行的安全性和可靠性。In order to meet the needs of unattended substation operation, must achieve high-frequency channel remote test function, instead of the present manual test in field to ensure the reliable operation of the channel. This paper combined with the actual in field of chaohu power supply company, the key issues involved in the high-frequency channel remote test are studied and described, manual test of high-frequency channel in centralized control center and automatic test of channel in monitor end have realized by the transceiver of line protection control in measure and control unit of controlled station end. Application software was developed in monitor system of centralized control center, to monitor and judge testing procedure, the result of testing is inform operators and transmitting dispatching center in the form of alarm. The system is easy to use, friendly interface, clear result, help to improve the high-frequency protection operating safety and reliability.
