摘 要:为确保青藏交直流联网工程输电线路稳定高效运行,为该输电线路的在线监测通信网络设计了一种"光纤通信为主,无线保真(WiFi)接入为辅"的基于专网的后端汇集方案。考虑到青藏线的实际情况,青藏线在线监测系统的数据传输可采用3种通信方式:对于杆塔上有光纤复合架空地线的光纤接线盒(OFSC)的情况,采用直接光纤通信方式;对于杆塔上没有光纤接线盒但在视距范围内的情况,采用WiFi+光纤通信方式;对于杆塔上没有光缆接续盒且在非视距的情况,采用WiFi中继接力+光纤通信方式,无线传输到光纤接线盒之间需要加装无线中继设备进行接力传送数据。目前,青藏交直流联网工程通信状况良好。In order to ensure the stable high-effective operation of the transmission lines in the Qinghai-Tibet AC/DC interconnection project, we propose a private-network-based back-end collection scheme that mainly relies on optical fiber communication while making wireless fidelity(WiFi) subsidiary. When the circumstances of the Qinghai-Tibet line are taken into consideration, there are three options of communication mode for data transmission of the Qinghai-Tibet on-line monitoring system: the direct optical fiber communication mode for the towers with optical fiber splice closures (OFSC) of optical-fiber-composite overhead ground wires; the WiFi q-optical fiber communication mode for the towers without OFSC but in the stadia range; the WiFi relay and optical fiber communication mode for the towers without OFSC and beyond the stadia range, and in this case, wireless relay equipment should be added between the wireless transmission and the closures. The practical communication network of the Qinghai-Tibet AC/DC interconnection project has been working in good condition.
