Xinhua News Agency, Xining, December 9th (Reporters Luo Xiaofei, Zhang Hongxiang) The reporter learned from the State Grid Qinghai Electric Power Company that since the Qinghai-Tibet Interconnection Project was put into operation, the project has been in safe operation for the 10th anniversary, and the two-way cumulative power transmission exceeded 14.3 billion kWh. It emits 11.7 million tons of carbon dioxide.
In December 2011, the Qinghai-Tibet Interconnection Project was officially put into operation, realizing the interconnection of the Tibet Power Grid and the Northwest (Qinghai) Power Grid, ending the history of the Tibet Power Grid's isolated grid operation.
The Qinghai-Tibet interconnection project, known as the "Electric Power Road", starts from Xining, Qinghai in the east, to Lhasa, Tibet in the west, with a total length of 2,530 kilometers. It is the world's highest-altitude DC transmission project and the longest transmission line through permafrost.
Li Zhiwei, head of the Qaidam converter station of the State Grid Qinghai Electric Power Maintenance Company, said that up to now, the Qinghai-Tibet interconnection project has sent 8.65 billion kWh of electricity to Tibet and 5.67 billion kWh of hydropower to Tibet, helping Tibet to realize resource advantages and economic advantages. Conversion.
The Qinghai-Tibet Interconnection Project traverses different ecosystems such as alpine deserts, plateau meadows, swamps, wetlands, and alpine shrubs. There are national nature reserves such as the Hoh Xil Nature Reserve and the Sanjiangyuan Nature Reserve along the route.
During the construction period, the construction unit adopted a variety of methods to protect the ecology. At present, the vegetation around the channel and the base of the tower has been restored naturally.
In addition, in order to reduce the impact of operation and maintenance inspections on the fragile ecology, State Grid Qinghai Electric Power adopted the "drone + helicopter + manual inspection" three-dimensional inspection method to effectively reduce the interference to the ecological environment along the line.
