On April 20, with the connection of the Bingjin UHV line visualization system to the emergency command center display platform of the State Grid Zhejiang Electric Power Company, it marked the launch of the full coverage project
of high-definition video real-time online monitoring of UHV line channels.
It is reported that in the past, the line online monitoring system often used the method of renting the resources of public network operators such as mobile to transmit video surveillance services
.
However, due to the narrow channel bandwidth, it is often difficult to provide high-definition picture quality, and at the same time, the rental cost is high and there are many
fault repair links.
In the Bingin UHV visualization system, the company builds its own communication network, combines the actual line, adopts the hybrid networking mode of various communication technologies such as optical fiber point-to-multipoint to complete the communication access problem of terminal equipment, and completes signal aggregation and remote transmission
through the nearby access to the substation optical network.
It is reported that the bandwidth of the access channel of the new visualization system is 10 times that of the previous public network bandwidth, realizing high-definition visualization
.
The company plans to complete the full coverage of high-definition video surveillance of UHV line channels by March 2017, involving a total of 1827.
3 km UHV AC and DC transmission lines and 2998
bases of pole towers in Zhejiang Power Grid 。 Through the construction of high-definition video real-time online monitoring, the company hopes to achieve the average online rate of various online monitoring devices is not less than 98%, the device defect elimination time is not more than 5 working days, the data availability rate of each set of monitoring devices is not less than 98%, and the daily inspection of the main equipment of the line is adjusted from manual inspection mode to remote monitoring, etc.
, further strengthen the safety of UHV transmission line channels, effectively improve the UHV safety management level, and ensure the smooth operation
of power grids at all levels.
