一种变电站高频保护通道状态的远程测试系统及方法
摘要：
一种变电站高频保护通道状态的远程测试系统及方法，所述的系统包括一与远方运维站相连的、变电站内已有的自动化测控系统，一与自动化测控系统相连的、可接受遥控指令的现有高频保护装置收发信机，所述自动化测控系统的遥控回路中并入有所述高频保护装置收发信机的通道测试点；所述的方法包括：1）下达遥控测试指令，远方运维站的工作人员利用主站监控器，通过变电站内的自动化监控系统向高频保护装置的收发信机下达进行高频保护通道状态测试的遥控指令，所述的高频保护装置的收发信机将现场测试结果以仪表指示形式显示在测试仪表上；2）测试结果回传并监控显示，通过配置在测试仪表前面的摄像头，将测试结果的图像通过信息图像系统回传至远方运维站的主站监控器上。
摘要（英）：

The invention provides a remote test system and method for a substation high frequency protection channel state. The system comprises an automation measurement and control system which has already existed in a substation and is connected with a remote operation and maintenance station, and an existing high frequency protection device transceiver which is connected with the automation measurement and control system and is capable of receiving a remote control instruction, wherein a remote control loop of the automation measurement and control system is integrated with channel test points of the high frequency protection device transceiver. The method comprises the following steps: 1) giving a remote control test instruction: work personnel in the remote operation and maintenance station utilize a master station monitor to give the remote control instruction for carrying out high frequency protection channel state test to the transceiver of a high frequency protection device through the automation monitoring and control system in the substation, and the transceiver of the high frequency protection device displays on-site test results on a test instrument in a instrument indicating manner; and 2) returning the test results and monitoring display: pictures of the test results are returned to the master station monitor of the remote operation and maintenance station through a message picture system and through a camera configured in front of the test instrument.
